- a light assembly 17 mounted to the frame 12 that is used to illuminate the tanks 16
- an electrical panel (not illustrated) that is used to provide timers (not illustrated) for wash down of the tanks 16
- temperature control devices not illustrated
- the position of the spacers 18 aids the user in the access and maintenance of the tanks 16 themselves.
- the tanks 16 of the present invention include freshwater tanks 16 f to hold freshwater for marine life that live in freshwater, and saltwater tanks 16 s to hold saltwater for marine life that live in saltwater.
- the design of the freshwater tank 16 f is substantially a mirror image of the saltwater tank 16 s.
- the saltwater tanks 16 s and the freshwater tanks 16 f may be interchangeably positioned in the tank cavities 14 of the frame 12 .
- all of the tanks 16 are designed to securely fit interchangeably within each of the tank cavities 14 of the frame 12 to have immediate access to either a freshwater supply and drain or a saltwater supply and drain.
- both the freshwater tank 16 f and the saltwater tank 16 s may be substantially square or rectangular, having a front wall 26 , a right side wall 28 connected to one end of the front wall 26 , a left side wall 30 connected to the front wall 26 and extending substantially parallel to the right side wall 28 , and a rear wall 32 connected between the right side wall 28 and the left side wall 30 .
- the dimensions of each tank 16 are substantially 15 inches by 15.5 inches by 11 inches.
- each tank 16 s, 16 f is able to hold approximately eleven gallons of water, not including any marine life or decorations that may be included in each tank 16 . It should be noted, however, that the tanks 16 may have any shape as desired by the user.
- the tanks 16 have a substantially trapezoidal shape, with one side wall 28 , 30 being shorter than the opposite side wall 28 , 30 .
- Such a design will assist the user in determining which tanks 16 hold freshwater and saltwater, and may also prevent the user from filling the tanks 16 with the wrong type of water.
- a filter wall 34 is additionally used in each tank 16 s, 16 f to define a draining area 36 or overflow box within the respective tank 16 .
- the filter wall 34 in the saltwater tank 16 s, the filter wall 34 is positioned between the rear wall 32 and the left side wall 30 , while in freshwater tank 16 f, the filter wall 34 is connected between the rear wall 32 and the right side wall 28 .
- the filter wall 34 includes a series of filter openings 35 traversing therethrough, such that the water in the tanks 16 s, 16 f may easily flow through the filter wall 34 into the draining area 36 .
- the draining area 36 or overflow box defined by the filter wall 34 in each fishing tank 16 surrounds a tank outlet 38 , the use of which is described herein.
- the filter openings 35 through the filter wall 34 allow the water in the tank 16 to flow into the draining area 36 without permitting undesired items from the tank 16 (such as rocks, waste, or marine life) to flow into the draining area 36 .
- both the freshwater tank 16 f and the saltwater tank 16 s allows the tanks 16 to be securely fit into the tank cavities 14 of the frame 12 .
- the respective position of the tank 16 s in the tank cavities 14 allows for the proper handling of both saltwater and freshwater in the aquarium assembly 10 , both in the accumulation of the suitable water (i.e., freshwater or saltwater) in the respective tank 16 and the dispersion of that water from the tank 16 into a corresponding filtering system, either a freshwater filtering system 42 or a saltwater filtering system 44 .
- the freshwater tank 16 f and saltwater tank 16 s may be marked for easy identification and foolproof use in the aquarium assembly 10 . That is, each tank 16 has a substantially transparent front wall 26 for viewers to be able to see the marine life contained in the tanks 16 , while the remaining sides 28 , 30 , and 32 may be a distinct color or designation to assist users in determining whether the tank 16 is used to hold freshwater or saltwater.
- the sides 28 , 30 , and 32 of the freshwater tank 16 f could be blue, while the sides 28 , 30 , and 32 of the saltwater tank 16 s could be black.
- the user may easily discern the proper tank 16 without having to examine the configuration of the tank 16 or comparing the tank 16 with the position of the corresponding draining basin 50 in the tank cavity 14 .
- additional means for identifying tank 16 s could be used in the present invention following this color-coding example, including using varying tank shapes to coordinate with the contents of the tank 16 .
- each tank cavity 14 in the frame 12 is designed such that, when the tank 16 is fully and securely positioned in the tank cavity 14 , the position of the tank outlet 38 of the tank 16 will correspond with a basin opening 51 of the draining basin 50 (either a saltwater draining basin 50 s or a freshwater draining basin 50 f ). More specifically, the freshwater tank outlet 38 f will coincide with the respective freshwater basin opening 51 f for the freshwater draining basin 50 f, and the saltwater tank outlet 38 s will coincide with the respective saltwater basin opening 51 s for the saltwater draining basin 50 s. Thus, each tank outlet 38 is positioned in the respective tank 16 to correspond with the desired basin opening 51 .
- the saltwater tank outlet 38 s is positioned in the draining area 36 located at the left rear corner of the tank cavity 14
- the freshwater tank outlet 38 f is positioned in the draining area 36 located at the right rear corner of the tank cavity 14 .
- the aquarium assembly 10 also provides a means for filling the respective tank 16 with the proper type of water for the particular tank 16 , as shown in FIGS. 6, 11 , and 12 . That is, a freshwater spout 46 f or conduit and a saltwater spout 46 s or conduit are positioned within each tank cavity 14 above the tank 16 .
- the freshwater spout 46 f is provided above the tank 16 to quickly fill the freshwater tank 16 f with freshwater.
- saltwater spout 46 s is provided above the tank 16 to quickly fill the saltwater tank 16 s with saltwater.
- a tank tube 47 may be affixed to a filling aperture 49 in the tank 16 to be connected with a corresponding spout 46 .
- each tank tube 47 is positioned to correspond with a spout 46 such that only the proper type of water (freshwater or saltwater) will be dispensed into the respective tank 16 . Since the saltwater spout 46 s and the freshwater spout 46 f are approximately fifteen inches apart in each tank cavity 14 , each saltwater tank 16 s and freshwater tank 16 f may only be attached to the appropriate freshwater spout 46 f or saltwater spout 46 s due to the position of the corresponding tank tube 47 with each tank 16 .
- these spouts 46 may be labeled for easy identification by the user. That is, the freshwater spout 46 f may be blue to correspond with the color of the freshwater tanks 16 f, while the saltwater spout 46 s may be black to correspond with the color of the saltwater tanks 16 s.
- identification measures allow the user to easily discern which spout 46 s, 46 f is to be used with each tank 16 s, 16 f.
- the user may incorporate quick disconnect fittings (not illustrated) to the tank tubes 47 s, 47 f and spouts 46 s, 46 f having varying orientations, which will prevent a freshwater spout 46 f from being connected with a saltwater tank tube 47 s, and vice versa. These measures prevent a user from contaminating either water supply with the incorrect type of water.
- Each tank 16 additionally includes a stand-pipe 48 , closure rod, plug, or other means for corking or closing the tank outlet 38 in the draining area 36 .
- the stand-pipe 48 will prevent undesired discharge of water from the tank 16 through the tank outlet 38 .
- the stand-pipe 48 is preferably hollow, such that water in the tank 16 will drain through the stand-pipe 48 once the water level reaches the height of the stand-pipe 48 in the tank 16 .
- Such an embodiment prevents the user from accidentally overfilling the tank 16 and potentially mixing the freshwater and saltwater reservoirs.
- the user is able to control the level of water in each individual tank 16 by adjusting the height of the stand-pipe 48 that is used in the particular tank 16 .
- the user will determine whether a freshwater tank 16 f or a saltwater tank 16 s is to be used in a particular tank cavity 14 of the frame 12 .
- the user will insert the stand-pipe 48 through the draining area 36 to engage the corresponding tank outlet 38 so that the tank 16 will retain water rather than dispersing it through the tank outlet 38 .
- the user will then insert the proper tank 16 into the tank cavity 14 according to the user's desired arrangement of the freshwater marine life and saltwater marine life.
- the user will connect the water spout 46 with the corresponding tank tube 47 , or direct the proper water spout 46 s, 46 f into the corresponding tank 16 s, 16 f, and engage a water freshwater valve (not illustrated) corresponding to the freshwater spout 46 f or a saltwater valve (not illustrated) corresponding to the saltwater spout 46 s to allow the desired type of water to flow into the tank 16 .
- a water freshwater valve not illustrated
- a saltwater valve not illustrated
- the user When the user is ready to replace a freshwater tank 16 f with a saltwater tank 16 s, or vice versa, or when the user is ready to clean a respective tank 16 , the user will drain the water from the tank 16 by removing the stand-pipe 48 from the tank outlet 38 , thereby allowing the water to flow in the draining basin 50 . After the water has completely dispersed from the tank 16 into the proper draining basin 50 , the user is able to easily remove the tank 16 from the tank cavity 14 of the frame 12 . The tank 16 may then be cleaned and reinserted into the frame 12 , or a separate tank 16 may be chosen that will be able to hold either saltwater or freshwater.
- the user is able to quickly switch between a freshwater tank 16 f with a saltwater tank 16 s.
- a freshwater tank 16 f with a saltwater tank 16 s.
- it will take less than five minutes to exchange one tank 16 filled with water with another tank 16 also filled with water.
- the water will flow into a draining basin 50 positioned below the tank 16 .
- the saltwater draining basin 50 s is positioned under the saltwater tank outlet 38 s of each tank cavity 14
- the freshwater draining basin 50 f is likewise positioned under the freshwater tank outlet 38 f of each tank cavity 14 .
- conduit 52 preferably two-inch conduit leading to a corresponding freshwater sump 53 f or saltwater sump 53 s positioned in each frame 12 beneath the various tank cavities 14 .
- the freshwater sump 53 f and the saltwater sump 53 s are positioned proximate each other, and are joined to corresponding freshwater sumps 53 f and saltwater sumps 53 s of other frames 14 via sump conduit 55 (freshwater sump conduit 55 f and saltwater sump conduit 55 s ).
- the freshwater sump conduit 55 f is preferably four inches in diameter, while the saltwater sump conduit 55 s is preferably two inches in diameter.
- the unfiltered water in the sump conduit 55 is then delivered to the filtering assembly 60 that includes a saltwater filtering apparatus 62 and a freshwater filtering apparatus 64 .
- the present design eliminates any concern of cross contamination of the saltwater with the freshwater reservoir and vice versa.
- the process for filtering water begins with water being emptied from the various tank 16 into the draining basins 50 .
- each saltwater tank 16 s will drain water into the respective saltwater draining basin 50 s and each freshwater tank 16 f will drain water into the respective freshwater draining basin 50 f supported by the frame 12 below the corresponding tank 16 .
- the draining basin 50 will regulate the flow of water from the saltwater or freshwater tank 16 .
- Drain conduit 52 connects the saltwater and freshwater draining basins 50 s, 50 f with the respective freshwater and saltwater sumps 53 f, 53 s, which are then connected to the filtering apparatus 62 , 64 , such that the unfiltered water can be filtered and reused.
- both the freshwater filtering apparatus 62 and the saltwater filtering system 64 include a gravity flow filtration system, as described in the Applicants' U.S. Pat. No. 6,641,718.
- the saltwater filtering apparatus 62 is substantially similar to the freshwater filtering apparatus 64 , although the freshwater filtering apparatus 64 includes a different skimming apparatus, as discussed in more detail below.
- either systems may include other filtering systems that properly filter the water.
- unfiltered water is delivered into a corresponding sump 40 f, 40 s, where it is then directed through filtering socks 63 into a filtered sump 40 f.
- the filtered water then flows into either a freshwater sump 40 f or saltwater sump 40 s to be skimmed and then be distributed to the respective tanks 16 s, 16 f as desired by the user.
- the freshwater filtering apparatus 62 and the saltwater filter apparatus 64 are housed in a filter covering 65 .
- each respective saltwater filtering apparatus 62 or freshwater filtering apparatus 64 will be skimmed by either a saltwater skimmer 70 or a freshwater skimmer 90 .
- a conventional water skimmer is in essence a reaction chamber in which a mixture of water and very fine bubbles are injected into the unclean water to create a foam.
- the bubbles have a weak electrical surface charge due to the orientation of the molecules that compose them, and the bubbles are used to adhere to dissolved and particulate organic matter in the water column.
- organic matter can be waste from fish and other aquarium life forms, tap water, uneaten food, and many other sources. This waste will typically have an electrical surface charge that is opposite of the bubbles created by the skimmer.
- a conventional saltwater skimmer 70 the waste is removed by forcing the foam with the waste material up through a wide foam lift tube 76 or column into a waste receptacle 74 or collection cup, where the waste is then trapped.
- the waste receptacle 74 is emptied as needed by the aquarium owner to prevent undesired algae and bacteria from feeding on the organic waste. If this organic waste is not contained, the algae and bacteria will form layers of hair or slime within the aquarium. The layers of hair and slime are an indication of a poorly maintained system in which few desirable life forms will thrive, and they are not aesthetically pleasing to the owner. As a result, the goal is to remove this organic material from the saltwater using the saltwater skimmer 70 .
- the aquarium assembly 10 of the present invention preferably includes both a saltwater skimmer 70 and a freshwater skimmer 90 .
- Each skimmer 70 , 90 includes a corresponding skimming tank 72 , 92 , with the foam collection cup 74 , 94 positioned at the top of the tank 72 , 92 and a venturi valve 93 that is used as a means to deliver both the water to be treated and also the air for generating the microscopic bubbles to attract waste.
- the venturi valve 93 is mounted to a water supply tube (not illustrated) within the skimming tank 72 , 92 with an air supply tube 95 connected to the mid-portion of the venturi valve 93 .
- the venturi valve 93 has one entry for air and one entry for water, with an exit for the air-water froth or foam.
- the internal part of the venturi valve 93 is designed so that water will flow through the valve 93 forcefully.
- air is drawn into the central portion of the valve 93 through the air tube.
- the higher the pressure of the water entering the venturi valve 93 the more air that will be drawn into the venturi valve 93 .
- the more air that is drawn in the more bubbles that are formed and the smaller they are.
- the air-water froth mixture therefore exits the venturi valve 93 at a fast rate, creating a vortex within the skimmer tank 72 , 92 to drive the foam into the collection cup 74 , 94 .
- the undesired organic material is trapped and removed from the aquarium assembly 10 .
- a conventional foam collection cup 74 is used in the saltwater skimmer 70 .
- a conventional collection cup 74 has a single wide foam lift tube 76 that is mounted at the base of the collection cup 74 .
- the foam in the saltwater skimmer 70 is forced upward through the wide foam lift tube 76 , and the foam thereby enters and is trapped within the foam collection cup 74 .
- this foam collection cup 74 design works well with saltwater skimmers 70 , such designs have not been successful with freshwater skimmers 90 .
- the understood reason for failure in freshwater skimmers 90 is due to the increased weight of the freshwater. That is, saltwater has a lighter weight, and therefore easy to draw foam into the collection cup 74 . Contrarily, freshwater is heavy, making it more difficult to get the foam with organic waste material through the single wide foam lift tube 76 into the collection cup 74 used in saltwater skimmers 70 .
- the present invention provides a freshwater foam collection cup 94 shown in FIGS. 18 and 19 .
- the freshwater foam collection cup 94 includes multiple narrow foam lift tubes 96 in the collection cup 94 rather than a single wide foam lift tube 76 (as provided in the saltwater collection cup 74 ).
- the multiple narrow foam lift tubes 96 are joined with the base of the collection cup 94 , providing a connection to the skimming tank 92 below.
- the narrow foam lift tubes 96 thereby draw the freshwater foam from the freshwater skimming tank 92 into the collection cup 94 . That is, since the freshwater foam heavy, it will take less energy for the foam to get through the multiple small or narrow foam lift tubes 96 rather than one large foam lift tube as provided for in the saltwater cup 94 .
- a protection plate (not illustrated) is provided to the top of the collection cup 94 to prevent the overfilling of the foam in the collection cup 94 .
- the freshwater foam collection cup 94 is removably attached to the upper end of a foam concentration chamber 97 .
- the foam accumulates in the foam collection cup 94 until full, and then the foam is easily discarded by the user.
- a cap 98 fits removably on top of the freshwater foam collection cup 94 to cause the accumulated foam to remain in the collection cup 94 while allowing air to escape.
- the cap 98 is a clear, one-inch thick device that is easily removed from the freshwater foam collection cup 94 .
- the filtered water is ready to be reintroduced into the tanks 16 . That is, the skimmed freshwater is directed to the freshwater filtered sump 40 f below the freshwater skimmer 90 , and the skimmed saltwater is directed to the saltwater sump 40 s below the saltwater skimmer 70 .
- a saltwater pump 41 s is connected to the saltwater sump 40 s to force the saltwater into conduit 52 to reintroduce the saltwater into the various respective saltwater tanks 16 s included by the user.
- a freshwater pump 41 f is connected to the freshwater sump 40 f to force the freshwater into conduit 52 f to reintroduce the filtered freshwater into the respective tank 16 s.
- the pumps 41 f , 41 s may be housed in one of the frames 12 , or within the filter covering 65 .
- the pumps 41 f , 41 s and conduit 52 connect the respective water reservoirs or sumps 40 s, 40 f with the corresponding freshwater spout 46 f or saltwater spout 46 s, as described above.
- Only one pump 41 is needed for the various frames 12 and tank cavities 14 , although the size of the pump 41 may be varied as required to deliver water to a greater number of tanks 16 through the spouts 46 . From the spouts 46 , the water may be reintroduced to the respective freshwater tanks 16 f or saltwater tank 16 s.
- the present invention solves multiple problems for retailers and other aquarium owners.
- the present assembly is easily adjusted according to the retailers inventory on hand and the retailers desire to market the marine life to customers. That is, the aquarium assembly 10 allows retailers to easily exchange saltwater tank 16 s and freshwater tank 16 f according to the number of the saltwater marine life and freshwater marine life that the retailer has in inventory.
- the retailer is able to position the various tank 16 in the frame 12 in a way to prominently display the marine life that are most desired to be sold.
- the aquarium assembly 10 which may be connected to a central filtering system, may fit in an area that is 51 inches by 21 inches by 81 inches, which is more compact that conventional display aquariums.
- the tanks 16 of the present aquarium assembly 10 illustrated in FIG. 1 may hold up 180 gallons of water, while a conventional comparable display aquarium will hold only 110 gallons of water.
- the present aquarium assembly 10 incorporates a more efficient use of space than that of comparable aquariums, in that the frame 12 completely encloses the tank 16 and the conduits 52 used to fill and drain the respective tank 16 s. Furthermore, the conduit 52 is aligned to further compact the plumbing. This reduces the space that is required by the plumbing.
- any tank 16 may be replaced by either a freshwater tank 16 f or a saltwater tank 16 s at any time, allowing the user to easily switch between a saltwater display and a freshwater display, while further providing the user with a simple way to clean the tank 16 that has been removed from the frame 12 .
- This allows the user to simply arrange the tanks 16 f, 16 s according to the inventory and according to any marketing plans held by the user.
- the present aquarium assembly 10 is desirable with residential tank 16 as well as commercial tank 16 . That is, the aquarium assembly 10 provides ease of use for the aquarium owner to position fish in the desired location at the desired time, as would be useful to both hobbyists as well as marine life store owners. Furthermore, the present design allows users to clean one tank 16 without having to replace or adjust the surrounding tanks 16 .

Abstract
An aquarium assembly having a frame defining a series of tank cavities. The frame will support both freshwater tanks and saltwater tanks, which are interchangeable within the tank cavities. A saltwater spout is positioned above said tank cavity such that said saltwater spout exclusively connects with the saltwater tank to fill the tank. A freshwater spout is positioned above said tank cavity such that said freshwater spout exclusively connects with the freshwater tank to fill the tank. The tanks include drains specifically positioned according to the water held by the tank, such that saltwater will drain to a saltwater filter and freshwater will drain to a freshwater filter. The filtered water is then redirected to the frame and the tanks where desired by the user. The freshwater filter further includes a skimming cup design that efficiently skims the unfiltered freshwater to be returned to the freshwater tanks.
Description
- The present application claims priority to U.S. Provisional Patent Application No. 60/530,998, filed on Dec. 18, 2003, incorporated herein by reference.
- The present invention is related to aquarium displays for displaying fish and other aquatic life in freshwater and saltwater environments. More specifically, the present invention relates to a aquarium assembly providing for the simple and quick interchange of saltwater tanks and freshwater tanks within a central frame. Even more specifically, the present invention is related to an aquarium assembly interchangeably holding freshwater and saltwater tanks for corresponding marine life, with the design having a freshwater skimming apparatus to clean and reuse freshwater and a saltwater skimming apparatus to clean and reuse saltwater for the various corresponding freshwater and saltwater tanks.
- In the field of aquarium displays it is desirable to display various species of fish and other aquatic life in a way that they can be closely observed by a viewer in a convenient manner. This is particularly true in a retail sales setting, where the various types of aquatic life are displayed for customers interested in purchasing such aquatic life. Consequently, it is advantageous for retailers to be able to advertise both freshwater aquatic life and saltwater aquatic life for users to decide on their purchase, and to be able to adjust their displays quickly and efficiently according to their inventory on hand.
- Such aquarium displays encounter various problems. For instance, the store owner's product will vary daily, such that it is difficult to determine how to allocate space for freshwater life and saltwater life. Another conflict with the goal of efficient advertising of inventory is the necessity to maximize the volume of water in a display per square foot of floor space occupied by the display, to achieve maximum economy in floor space used. This is a practical consideration in a retail setting, as floor space is at a premium. Consequently, it is advantageous to compact the size of the wall units while maintaining the size of the aquariums being viewed by customers.
- Furthermore, in the combination of freshwater and saltwater tanks, it is important to be able to efficiently filter and reuse the water from the tanks. While saltwater skimmers are commonly used, an efficient freshwater skimmer design has not previously been designed. As a result, the freshwater skimmer of the present invention is advantageous for the present design as well as with other aquariums.
- The present invention provides an aquarium assembly having a frame defining a series of tank cavities. The frame is operable to support both freshwater tanks and saltwater tanks, which are interchangeable within the tank cavities. A saltwater spout is positioned above the tank cavity such that the saltwater spout may exclusively connect with the saltwater tank to fill the saltwater tank accordingly. A freshwater spout is positioned above the tank cavity such that the freshwater spout may exclusively connect with the freshwater tank to fill the freshwater tank accordingly.
- Each tank includes an inner surface and an outer surface, with a filter wall connected to said inner surface of said tank to surround a tank outlet. In a freshwater tank, the tank outlet is in a first position complementary to a freshwater drain, while in a saltwater tank, the tank outlet is in a second position complementary to a saltwater drain. The filter wall defines a series of filter openings, such that water contained in the tank may flow through the filter walls and through the tank outlet to the corresponding drain.
- Each saltwater drain and freshwater drain is connected to a corresponding saltwater filter apparatus to receive saltwater from said tank, and a corresponding freshwater filter apparatus to receive freshwater from said tank. The freshwater filter apparatus includes a skimmer tank, a freshwater foam collection cup affixed to said skimmer tank, and a valve connected to said skimmer tank to force air and water into said skimmer tank to create freshwater foam in the skimmer tank. The freshwater foam collection cup includes a series of lift tubes traversing the collection cup, which allow the freshwater foam to be drawn into the collection cup to remove impurities from the freshwater.

FIG. 20 is a rear perspective view of the aquarium assemblies of the present invention, with the back wall being removed from the aquarium assemblies. - Referring now to the
FIGS. 1-6 , the present invention for aaquarium assembly 10 is illustrated. Theaquarium assembly 10 is a wall unit aquarium having aframe 12 or housing withmultiple tank cavities 14 that are able to support various marine lifeaquatic tanks 16. Eachtank 16 is either afreshwater tank 16 f (seeFIGS. 7 and 8 ) or a saltwater tank 16 s (seeFIGS. 9 and 10 ). In the embodiment illustrated inFIGS. 7-10 , each saltwater tank 16 s has a shape that is substantially a mirror image of the shape of eachfreshwater tank 16 f, the use of which is described herein. - In the example shown in
FIGS. 1-6 , theframe 12 of theaquarium assembly 10 has ninetank cavities 14 to receive nineindividual tanks 16. Specifically, there are three rows oftank cavities 14, with threetank cavities 14 on each row. The number oftank cavities 14 may vary, however, according to the number desired to be used in theaquarium assembly 10 by the user. Aspacer 18 is preferably provided above each row oftank cavities 14, with thespacer 18 providing room to allow the operator to access the eachparticular tank 16. A pair ofspacer doors 20 may be mounted to theframe 12 at the position of thespacer 18, with thespacer doors 20 protecting and hiding the plumbing of theaquarium assembly 10 to maintain a pleasant exterior appearance of theaquarium assembly 10. Thespacer doors 20 additionally provide easy and quick access to the spouts or conduit 46 of theaquarium assembly 10 as well as thetanks 16. Thespacers 18 may further protect a light assembly 17 (seeFIG. 6 ) mounted to theframe 12 that is used to illuminate thetanks 16, an electrical panel (not illustrated) that is used to provide timers (not illustrated) for wash down of thetanks 16, or temperature control devices (not illustrated), such as chillers or heaters, that are used to control the living environment for the marine life in therespective tanks 16. Finally, the position of thespacers 18 aids the user in the access and maintenance of thetanks 16 themselves. - As stated above, the
tanks 16 of the present invention includefreshwater tanks 16 f to hold freshwater for marine life that live in freshwater, and saltwater tanks 16 s to hold saltwater for marine life that live in saltwater. In the embodiment illustrated inFIGS. 7-10 , the design of thefreshwater tank 16 f is substantially a mirror image of the saltwater tank 16 s. In spite of the differing shapes or configurations of the saltwater tanks 16 s and thefreshwater tanks 16 f, the saltwater tanks 16 s and thefreshwater tanks 16 f may be interchangeably positioned in thetank cavities 14 of theframe 12. Furthermore, all of thetanks 16 are designed to securely fit interchangeably within each of thetank cavities 14 of theframe 12 to have immediate access to either a freshwater supply and drain or a saltwater supply and drain. - In the embodiment illustrated in
FIGS. 8 and 10 , both thefreshwater tank 16 f and the saltwater tank 16 s may be substantially square or rectangular, having afront wall 26, aright side wall 28 connected to one end of thefront wall 26, aleft side wall 30 connected to thefront wall 26 and extending substantially parallel to theright side wall 28, and arear wall 32 connected between theright side wall 28 and theleft side wall 30. The dimensions of eachtank 16 are substantially 15 inches by 15.5 inches by 11 inches. As a result, eachtank 16 s, 16 f is able to hold approximately eleven gallons of water, not including any marine life or decorations that may be included in eachtank 16. It should be noted, however, that thetanks 16 may have any shape as desired by the user. For example, in another embodiment illustrated inFIGS. 4-5 d, thetanks 16 have a substantially trapezoidal shape, with oneside wall opposite side wall tanks 16 hold freshwater and saltwater, and may also prevent the user from filling thetanks 16 with the wrong type of water. - A
filter wall 34 is additionally used in eachtank 16 s, 16 f to define a drainingarea 36 or overflow box within therespective tank 16. Referring toFIGS. 7-10 , in the saltwater tank 16 s, thefilter wall 34 is positioned between therear wall 32 and theleft side wall 30, while infreshwater tank 16 f, thefilter wall 34 is connected between therear wall 32 and theright side wall 28. Thefilter wall 34 includes a series offilter openings 35 traversing therethrough, such that the water in thetanks 16 s, 16 f may easily flow through thefilter wall 34 into the drainingarea 36. The drainingarea 36 or overflow box defined by thefilter wall 34 in eachfishing tank 16 surrounds atank outlet 38, the use of which is described herein. Thefilter openings 35 through thefilter wall 34 allow the water in thetank 16 to flow into the drainingarea 36 without permitting undesired items from the tank 16 (such as rocks, waste, or marine life) to flow into the drainingarea 36. - The shape of both the
freshwater tank 16 f and the saltwater tank 16 s allows thetanks 16 to be securely fit into thetank cavities 14 of theframe 12. Moreover, the respective position of the tank 16 s in thetank cavities 14 allows for the proper handling of both saltwater and freshwater in theaquarium assembly 10, both in the accumulation of the suitable water (i.e., freshwater or saltwater) in therespective tank 16 and the dispersion of that water from thetank 16 into a corresponding filtering system, either a freshwater filtering system 42 or a saltwater filtering system 44. - The
freshwater tank 16 f and saltwater tank 16 s may be marked for easy identification and foolproof use in theaquarium assembly 10. That is, eachtank 16 has a substantially transparentfront wall 26 for viewers to be able to see the marine life contained in thetanks 16, while the remainingsides tank 16 is used to hold freshwater or saltwater. For example, thesides freshwater tank 16 f could be blue, while thesides proper tank 16 without having to examine the configuration of thetank 16 or comparing thetank 16 with the position of thecorresponding draining basin 50 in thetank cavity 14. It should be noted that additional means for identifying tank 16 s could be used in the present invention following this color-coding example, including using varying tank shapes to coordinate with the contents of thetank 16. - Looking now to the exploded view shown in
FIG. 11 , eachtank cavity 14 in theframe 12 is designed such that, when thetank 16 is fully and securely positioned in thetank cavity 14, the position of thetank outlet 38 of thetank 16 will correspond with abasin opening 51 of the draining basin 50 (either asaltwater draining basin 50 s or afreshwater draining basin 50 f). More specifically, the freshwater tank outlet 38 f will coincide with the respective freshwater basin opening 51 f for thefreshwater draining basin 50 f, and the saltwater tank outlet 38 s will coincide with the respective saltwater basin opening 51 s for thesaltwater draining basin 50 s. Thus, eachtank outlet 38 is positioned in therespective tank 16 to correspond with the desiredbasin opening 51. - In the embodiments of the invention illustrated in
FIGS. 7 and 9 , the saltwater tank outlet 38 s is positioned in the drainingarea 36 located at the left rear corner of thetank cavity 14, while the freshwater tank outlet 38 f is positioned in the drainingarea 36 located at the right rear corner of thetank cavity 14. Consequently, when thesaltwater tank 16 f is inserted into atank cavity 14, the position of the saltwater draining area 36 s and the freshwater tank outlet 38 s of the saltwater tank 16 s will directly overlap the position of the saltwater basin opening 51 s of thesaltwater draining basin 50 s in thetank cavity 14, while the saltwater tank 16 s will cover and thereby obstruct the freshwater basin opening 51 f to thefreshwater draining basin 50 f. In a similar manner, when thefreshwater tank 16 f (seeFIGS. 8 and 10 ) is inserted into atank cavity 14, the position of the freshwater draining area 36 f and the freshwater tank outlet 38 f will directly overlap the position of the freshwater basin opening 51 f of thefreshwater draining basin 50 f, while thefreshwater tank 16 f will cover and thereby obstruct the saltwater basin opening 51 s of thesaltwater draining basin 50 s. As a result, this arrangement will prevent a user from mistakenly allowing saltwater to flow into a freshwater filtering system 42, and prevents freshwater from flowing into a saltwater filtering system 44. - In addition to the means for draining saltwater and freshwater from the respective tank 16 s, the
aquarium assembly 10 also provides a means for filling therespective tank 16 with the proper type of water for theparticular tank 16, as shown inFIGS. 6, 11 , and 12. That is, afreshwater spout 46 f or conduit and a saltwater spout 46 s or conduit are positioned within eachtank cavity 14 above thetank 16. For afreshwater tank 16 f, thefreshwater spout 46 f is provided above thetank 16 to quickly fill thefreshwater tank 16 f with freshwater. Similarly, for saltwater tank 16 s, the saltwater spout 46 s is provided above thetank 16 to quickly fill the saltwater tank 16 s with saltwater. - Looking further to
FIG. 11 , a tank tube 47 may be affixed to a fillingaperture 49 in thetank 16 to be connected with a corresponding spout 46. In particular, each tank tube 47 is positioned to correspond with a spout 46 such that only the proper type of water (freshwater or saltwater) will be dispensed into therespective tank 16. Since the saltwater spout 46 s and thefreshwater spout 46 f are approximately fifteen inches apart in eachtank cavity 14, each saltwater tank 16 s andfreshwater tank 16 f may only be attached to theappropriate freshwater spout 46 f or saltwater spout 46 s due to the position of the corresponding tank tube 47 with eachtank 16. Therefore, in this embodiment, only the saltwater tank 16 s will receive water from the saltwater spout 46 s through the saltwater tank tube 47 s, and only thefreshwater tank 16 f will receive water from thefreshwater spout 46 f through the freshwater tank tube 47 f. Furthermore, these spouts 46 may be labeled for easy identification by the user. That is, thefreshwater spout 46 f may be blue to correspond with the color of thefreshwater tanks 16 f, while the saltwater spout 46 s may be black to correspond with the color of the saltwater tanks 16 s. Such identification measures allow the user to easily discern which spout 46 s, 46 f is to be used with eachtank 16 s, 16 f. Finally, the user may incorporate quick disconnect fittings (not illustrated) to the tank tubes 47 s, 47 f and spouts 46 s, 46 f having varying orientations, which will prevent afreshwater spout 46 f from being connected with a saltwater tank tube 47 s, and vice versa. These measures prevent a user from contaminating either water supply with the incorrect type of water. - Each
tank 16 additionally includes a stand-pipe 48, closure rod, plug, or other means for corking or closing thetank outlet 38 in the drainingarea 36. Moreover, the stand-pipe 48 will prevent undesired discharge of water from thetank 16 through thetank outlet 38. The stand-pipe 48 is preferably hollow, such that water in thetank 16 will drain through the stand-pipe 48 once the water level reaches the height of the stand-pipe 48 in thetank 16. Such an embodiment prevents the user from accidentally overfilling thetank 16 and potentially mixing the freshwater and saltwater reservoirs. Furthermore, the user is able to control the level of water in eachindividual tank 16 by adjusting the height of the stand-pipe 48 that is used in theparticular tank 16. - In operation, the user will determine whether a
freshwater tank 16 f or a saltwater tank 16 s is to be used in aparticular tank cavity 14 of theframe 12. The user will insert the stand-pipe 48 through the drainingarea 36 to engage thecorresponding tank outlet 38 so that thetank 16 will retain water rather than dispersing it through thetank outlet 38. The user will then insert theproper tank 16 into thetank cavity 14 according to the user's desired arrangement of the freshwater marine life and saltwater marine life. Once thetank 16 has been securely positioned in thetank cavity 14, the user will connect the water spout 46 with the corresponding tank tube 47, or direct theproper water spout 46 s, 46 f into the correspondingtank 16 s, 16 f, and engage a water freshwater valve (not illustrated) corresponding to thefreshwater spout 46 f or a saltwater valve (not illustrated) corresponding to the saltwater spout 46 s to allow the desired type of water to flow into thetank 16. Once thetank 16 has been filled to the desired capacity, the user will shut off the valve. However, if the user forgets to shut off the valve in a timely manner, the excess water will be drained through the stand-pipe 48. The user will then be able to add the desired marine life to thetank 16. - When the user is ready to replace a
freshwater tank 16 f with a saltwater tank 16 s, or vice versa, or when the user is ready to clean arespective tank 16, the user will drain the water from thetank 16 by removing the stand-pipe 48 from thetank outlet 38, thereby allowing the water to flow in the drainingbasin 50. After the water has completely dispersed from thetank 16 into theproper draining basin 50, the user is able to easily remove thetank 16 from thetank cavity 14 of theframe 12. Thetank 16 may then be cleaned and reinserted into theframe 12, or aseparate tank 16 may be chosen that will be able to hold either saltwater or freshwater. Thus, the user is able to quickly switch between afreshwater tank 16 f with a saltwater tank 16 s. In most cases with thepresent aquarium assembly 10, it will take less than five minutes to exchange onetank 16 filled with water with anothertank 16 also filled with water. - Referring to
FIGS. 6, 11 , and 13-20, once the stand-pipe 48 has been removed from thetank outlet 38, the water will flow into a drainingbasin 50 positioned below thetank 16. As noted above, thesaltwater draining basin 50 s is positioned under the saltwater tank outlet 38 s of eachtank cavity 14, and thefreshwater draining basin 50 f is likewise positioned under the freshwater tank outlet 38 f of eachtank cavity 14. From therespective draining basin 50, the water will flow into conduit 52 (preferably two-inch conduit) leading to acorresponding freshwater sump 53 f or saltwater sump 53 s positioned in eachframe 12 beneath thevarious tank cavities 14. Looking toFIG. 20 , thefreshwater sump 53 f and the saltwater sump 53 s are positioned proximate each other, and are joined to correspondingfreshwater sumps 53 f and saltwater sumps 53 s ofother frames 14 via sump conduit 55 (freshwater sump conduit 55 f and saltwater sump conduit 55 s). The freshwater sump conduit 55 f is preferably four inches in diameter, while the saltwater sump conduit 55 s is preferably two inches in diameter. - The unfiltered water in the sump conduit 55 is then delivered to the
filtering assembly 60 that includes asaltwater filtering apparatus 62 and afreshwater filtering apparatus 64. By having two isolated plumbing systems for saltwater and freshwater, the present design eliminates any concern of cross contamination of the saltwater with the freshwater reservoir and vice versa. - The process for filtering water begins with water being emptied from the
various tank 16 into the drainingbasins 50. As discussed above, each saltwater tank 16 s will drain water into the respectivesaltwater draining basin 50 s and eachfreshwater tank 16 f will drain water into the respectivefreshwater draining basin 50 f supported by theframe 12 below the correspondingtank 16. The drainingbasin 50 will regulate the flow of water from the saltwater orfreshwater tank 16. Drainconduit 52 connects the saltwater andfreshwater draining basins saltwater sumps 53 f, 53 s, which are then connected to thefiltering apparatus - In the present embodiment, both the
freshwater filtering apparatus 62 and thesaltwater filtering system 64 include a gravity flow filtration system, as described in the Applicants' U.S. Pat. No. 6,641,718. Thesaltwater filtering apparatus 62 is substantially similar to thefreshwater filtering apparatus 64, although thefreshwater filtering apparatus 64 includes a different skimming apparatus, as discussed in more detail below. However, it is noted that either systems may include other filtering systems that properly filter the water. In the invention as illustrated, unfiltered water is delivered into a correspondingsump 40 f, 40 s, where it is then directed throughfiltering socks 63 into a filteredsump 40 f. From eachrespective filtering apparatus freshwater sump 40 f or saltwater sump 40 s to be skimmed and then be distributed to therespective tanks 16 s, 16 f as desired by the user. Looking toFIGS. 1 and 2 , thefreshwater filtering apparatus 62 and thesaltwater filter apparatus 64 are housed in a filter covering 65. - The unfiltered water in each respective
saltwater filtering apparatus 62 orfreshwater filtering apparatus 64 will be skimmed by either asaltwater skimmer 70 or afreshwater skimmer 90. As a bit of background, a conventional water skimmer is in essence a reaction chamber in which a mixture of water and very fine bubbles are injected into the unclean water to create a foam. The bubbles have a weak electrical surface charge due to the orientation of the molecules that compose them, and the bubbles are used to adhere to dissolved and particulate organic matter in the water column. Such organic matter can be waste from fish and other aquarium life forms, tap water, uneaten food, and many other sources. This waste will typically have an electrical surface charge that is opposite of the bubbles created by the skimmer. - In a
conventional saltwater skimmer 70, the waste is removed by forcing the foam with the waste material up through a widefoam lift tube 76 or column into awaste receptacle 74 or collection cup, where the waste is then trapped. Thewaste receptacle 74 is emptied as needed by the aquarium owner to prevent undesired algae and bacteria from feeding on the organic waste. If this organic waste is not contained, the algae and bacteria will form layers of hair or slime within the aquarium. The layers of hair and slime are an indication of a poorly maintained system in which few desirable life forms will thrive, and they are not aesthetically pleasing to the owner. As a result, the goal is to remove this organic material from the saltwater using thesaltwater skimmer 70. - The
aquarium assembly 10 of the present invention preferably includes both asaltwater skimmer 70 and afreshwater skimmer 90. Eachskimmer corresponding skimming tank foam collection cup tank venturi valve 93 that is used as a means to deliver both the water to be treated and also the air for generating the microscopic bubbles to attract waste. In particular, theventuri valve 93 is mounted to a water supply tube (not illustrated) within theskimming tank venturi valve 93. Theventuri valve 93 has one entry for air and one entry for water, with an exit for the air-water froth or foam. The internal part of theventuri valve 93 is designed so that water will flow through thevalve 93 forcefully. As the water flows through theventuri valve 93, air is drawn into the central portion of thevalve 93 through the air tube. The higher the pressure of the water entering theventuri valve 93, the more air that will be drawn into theventuri valve 93. The more air that is drawn in, the more bubbles that are formed and the smaller they are. The air-water froth mixture therefore exits theventuri valve 93 at a fast rate, creating a vortex within theskimmer tank collection cup collection cup aquarium assembly 10. - In the
saltwater skimmer 70, a conventionalfoam collection cup 74 is used. Such aconventional collection cup 74 has a single widefoam lift tube 76 that is mounted at the base of thecollection cup 74. The foam in thesaltwater skimmer 70 is forced upward through the widefoam lift tube 76, and the foam thereby enters and is trapped within thefoam collection cup 74. While thisfoam collection cup 74 design works well withsaltwater skimmers 70, such designs have not been successful withfreshwater skimmers 90. The understood reason for failure infreshwater skimmers 90 is due to the increased weight of the freshwater. That is, saltwater has a lighter weight, and therefore easy to draw foam into thecollection cup 74. Contrarily, freshwater is heavy, making it more difficult to get the foam with organic waste material through the single widefoam lift tube 76 into thecollection cup 74 used insaltwater skimmers 70. - To address this problem, the present invention provides a freshwater
foam collection cup 94 shown inFIGS. 18 and 19 . The freshwaterfoam collection cup 94 includes multiple narrowfoam lift tubes 96 in thecollection cup 94 rather than a single wide foam lift tube 76 (as provided in the saltwater collection cup 74). The multiple narrowfoam lift tubes 96 are joined with the base of thecollection cup 94, providing a connection to theskimming tank 92 below. The narrowfoam lift tubes 96 thereby draw the freshwater foam from thefreshwater skimming tank 92 into thecollection cup 94. That is, since the freshwater foam heavy, it will take less energy for the foam to get through the multiple small or narrowfoam lift tubes 96 rather than one large foam lift tube as provided for in thesaltwater cup 94. Furthermore, a protection plate (not illustrated) is provided to the top of thecollection cup 94 to prevent the overfilling of the foam in thecollection cup 94. - The freshwater
foam collection cup 94 is removably attached to the upper end of afoam concentration chamber 97. Thus, the foam accumulates in thefoam collection cup 94 until full, and then the foam is easily discarded by the user. Acap 98 fits removably on top of the freshwaterfoam collection cup 94 to cause the accumulated foam to remain in thecollection cup 94 while allowing air to escape. Thecap 98 is a clear, one-inch thick device that is easily removed from the freshwaterfoam collection cup 94. - Once the freshwater and saltwater have been skimmed of undesired waste, the filtered water is ready to be reintroduced into the
tanks 16. That is, the skimmed freshwater is directed to the freshwater filteredsump 40 f below thefreshwater skimmer 90, and the skimmed saltwater is directed to the saltwater sump 40 s below thesaltwater skimmer 70. Referring to the block diagram illustrated inFIGS. 6, 13 and 14, asaltwater pump 41 s is connected to the saltwater sump 40 s to force the saltwater intoconduit 52 to reintroduce the saltwater into the various respective saltwater tanks 16 s included by the user. Likewise, afreshwater pump 41 f is connected to thefreshwater sump 40 f to force the freshwater into conduit 52 f to reintroduce the filtered freshwater into the respective tank 16 s. As is illustrated inFIGS. 13 and 14 , thepumps frames 12, or within the filter covering 65. Moreover, thepumps conduit 52 connect the respective water reservoirs orsumps 40 s, 40 f with the correspondingfreshwater spout 46 f or saltwater spout 46 s, as described above. Only one pump 41 is needed for thevarious frames 12 andtank cavities 14, although the size of the pump 41 may be varied as required to deliver water to a greater number oftanks 16 through the spouts 46. From the spouts 46, the water may be reintroduced to therespective freshwater tanks 16 f or saltwater tank 16 s. - The present invention solves multiple problems for retailers and other aquarium owners. For retailers, the present assembly is easily adjusted according to the retailers inventory on hand and the retailers desire to market the marine life to customers. That is, the
aquarium assembly 10 allows retailers to easily exchange saltwater tank 16 s andfreshwater tank 16 f according to the number of the saltwater marine life and freshwater marine life that the retailer has in inventory. Furthermore, the retailer is able to position thevarious tank 16 in theframe 12 in a way to prominently display the marine life that are most desired to be sold. - Moreover, the
aquarium assembly 10, which may be connected to a central filtering system, may fit in an area that is 51 inches by 21 inches by 81 inches, which is more compact that conventional display aquariums. Further, thetanks 16 of thepresent aquarium assembly 10 illustrated inFIG. 1 may hold up 180 gallons of water, while a conventional comparable display aquarium will hold only 110 gallons of water. Thepresent aquarium assembly 10 incorporates a more efficient use of space than that of comparable aquariums, in that theframe 12 completely encloses thetank 16 and theconduits 52 used to fill and drain the respective tank 16 s. Furthermore, theconduit 52 is aligned to further compact the plumbing. This reduces the space that is required by the plumbing. - Since the
various freshwater tanks 16 f and saltwater tanks 16 s are interchangeable, they are easily removed from theframe 12 and replaced by anothertank 16. Therefore, anytank 16 may be replaced by either afreshwater tank 16 f or a saltwater tank 16 s at any time, allowing the user to easily switch between a saltwater display and a freshwater display, while further providing the user with a simple way to clean thetank 16 that has been removed from theframe 12. This allows the user to simply arrange thetanks 16 f, 16 s according to the inventory and according to any marketing plans held by the user. - Moreover, the
present aquarium assembly 10 is desirable withresidential tank 16 as well ascommercial tank 16. That is, theaquarium assembly 10 provides ease of use for the aquarium owner to position fish in the desired location at the desired time, as would be useful to both hobbyists as well as marine life store owners. Furthermore, the present design allows users to clean onetank 16 without having to replace or adjust the surroundingtanks 16. - Thus, although there have been described particular embodiments of the present invention of a new and useful AQUARIUM ASSEMBLY, it is not intended that such references be construed as limitations upon the scope of this invention except as set forth in the following claims.
