It is a schematic sectional drawing which shows the example of a use condition of the example of another fish breeding water tank tool same as the above. It is a photograph which shows the state after 2 days progress of one experiment of the fish breeding water tank tool same as the above, and after 12 days progress.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. The fish breeding aquarium tool 1 according to the embodiment of the present invention is a pottery that is fired by mixing at least porous charcoal powder and calcium carbonate powder in clay.

  The shape of the fish tank device 1 is not particularly limited. For example, as shown in FIG. 1, the fish tank device 1 can have a substantially cylindrical shape having a through hole 1 a along the central axis. Such a substantially cylindrical shape is used by being placed on the bottom of the water tank 2 alone, or is used by being attached to an aeration device 4 to which an air tube 3 is connected as shown in FIG. You can. Since the fish tank device 1 is a pottery, it can be easily shaped according to the required function. For example, in addition to the substantially cylindrical shape having the through-hole 1a, a flower pot shape that also serves as a container for plant growth, a coral shape, a tube shape that also serves as a fish hideout, a lava shape that also serves as an interior, a driftwood shape, etc. In addition, a rod shape or a simple granular shape is possible.

  The porous charcoal powder is, for example, a powder such as kun charcoal. Kum charcoal has a high water absorption rate. The calcium carbonate powder is a powder of limestone, for example. Clay has pores and can absorb water when fired, and is, for example, Shigaraki pottery. The mixing ratio of the porous charcoal powder, the calcium carbonate powder, and the clay can be, for example, about 20 wt%, about 10 wt%, and about 70 wt%, respectively.

  The temperature for firing the mixture of porous charcoal powder, calcium carbonate powder and clay is 650 ° C. or lower. The reason for firing at 650 ° C. or lower is to prevent the calcium carbonate from being chemically changed to calcium oxide. The lower limit of the firing temperature is a temperature at which the fired pottery can maintain the strength required for pottery, and is about 450 ° C., for example, depending on the type of clay. Firing is usually performed in an oxygen-free atmosphere.

  In such a fish breeding aquarium tool 1, clay becomes a fired pottery body part, and the pottery body part contains porous charcoal in a substantially uniform manner and calcium carbonate is dispersed in a substantially uniform manner. It is contained and held in many holes of charcoal and holes in the pottery body. Here, since the porous charcoal has a large number of pores and has a large surface area, it can be retained by containing a sufficiently large amount of calcium carbonate.

  In an environment where the water stored in the aquarium has become acidic due to feces or the like, fish are difficult to survive. Therefore, the calcium carbonate of the fish breeding aquarium tool 1 acts to return the acidity to neutrality. The water stored in the aquarium penetrates into the pottery body of the fish tank device 1, penetrates into the porous charcoal, and is retained in the pores of the porous charcoal and the porcelain body. To touch. When the water stored in the aquarium becomes acidic due to feces, etc., calcium carbonate dissolves into the acidic water that has permeated into the pores of the porous charcoal and the porcelain body. Return to neutral. The water which has returned to neutrality is mixed with other acidic water outside the fish tank device 1. If the water returns to neutral, the calcium carbonate will not dissolve. In this way, calcium carbonate dissolves efficiently as necessary, so that the action of returning to neutrality can be maintained for a long time.

  The inventor of the present application conducted an experiment to measure the change in PH by placing the fish-rearing tank device 1 in an acetic acid aqueous solution having a pH of 3.00. The fish tank device 1 at this time is fired at 600 ° C. with the mixing ratio of porous charcoal powder, calcium carbonate powder and clay in order of about 20 wt%, about 10 wt%, and about 70 wt%. It is what. For comparison, the pottery from which the calcium carbonate was removed from the fish tank device 1, that is, the mixture ratio of porous charcoal and clay was sequentially fired at 600 ° C. at about 20 wt% and about 80 wt%. An experiment in which pottery was placed in an acetic acid aqueous solution and an experiment in which the acetic acid aqueous solution was allowed to stand were performed. Table 1 shows the results of these experiments.

In the experiment in which the fish rearing tank tool 1 was put, the pH reached 6.78 after 7 days. In an experiment with a comparative pottery, PH = 3.92 after 7 days, and in an experiment in which an aqueous acetic acid solution was allowed to stand, PH = 3.13 after 7 days. Therefore, it turns out that the calcium carbonate of the fish breeding aquarium tool 1 acts to return the acidity to neutrality. In addition, the effect | action in this experiment is based on reaction shown in the following formula | equation.
CaCO ₃ + 2CH ₃ COOH → (CH ₃ COO) ₂ Ca + CO ₂ + H ₂ O

  In addition to porous charcoal and calcium carbonate, other materials such as zeolite can be mixed with clay and fired. Zeolite is excellent in adsorption of ammonia and the like. As described above, if the firing temperature is 650 ° C. or lower, the zeolite is prevented from being altered.

  Next, the fish rearing tank device 1 can be mixed with bacteria that form spores. Bacteria that form spores are, for example, Bacillus subtilis such as Bacillus subtilis. Bacillus subtilis is a highly safe bacterium that is not pathogenic. Bacteria that form spores germinate and proliferate when organic matter that is a nutrient source such as sea cucumbers is generated, decompose the organic matter, suppress the occurrence of sea cucumbers, etc. Return to the environment. When the organic matter disappears, it forms spores and does not die even in harsh environments such as drying. Thus, if necessary, the spore-forming bacteria germinate and proliferate, so that it is possible to maintain the effect of suppressing the occurrence of sea cucumbers and returning to an environment where fish can live easily for a long time.

  In order to mix such spore-forming bacteria, the powdered powder in the state of spore formation is placed in an aqueous solution, uniformly diffused and dissolved, and the fish-feeding tank device 1 is immersed in the aqueous solution. That's fine. Moreover, you may put the aqueous solution which the microbe mixed in the spray container, and may spray it to the fish breeding water tank tool 1. FIG. The pottery body part and the porous charcoal forming the fish breeding aquarium tool 1 absorb the aqueous solution mixed with the fungus due to its water absorption and mix the fungus into the fish breeding aquarium tool 1 itself. The bacteria live in the pores of the porous charcoal and the porcelain body.

  Bacillus subtilis is generally aerobic. When an aerobic bacterium such as Bacillus subtilis is used, the fish breeding aquarium tool 1 is placed near an air (bubble) generating device such as the aeration device 4 as shown in FIG. Alternatively, the fish tank device 1 may have a vertically long shape, for example, a flower pot shape as shown in FIG. 3 or FIG. 4 so that bacteria can easily live near the water surface WS. The fish tank device 1 in this case is extremely good for aerobic Bacillus subtilis because a capillary phenomenon occurs due to its water absorption in a fairly wide range near the water surface WS, water is contained, and oxygen is also contained. It becomes the environment. Therefore, when an organic substance that serves as a nutrient source such as a giant sea bream is generated, it germinates and proliferates, decomposes the organic matter, and can efficiently suppress the occurrence of the giant eel. In addition, what is shown in FIG.3 and FIG.4 puts soil etc. in the inside of the fish breeding water tank tool 1 so that a plant can be grown, and the side is so small that soil etc. does not jump out. A hole 1b is formed. In FIG. 3, the aeration device 4 is arranged at another place, and in FIG. 4, the storage container 5 is provided on the lower side of the fish breeding tank device 1 and the aeration device 4 is arranged therein. Is. Reference numeral 5a denotes an air (bubble) ejection hole. It is also possible to provide a device for circulating water and generate air by dropping water onto the water surface during the circulation.

  The inventor of the present application conducted an experiment in which a large amount of auko was placed in the aquarium, and the fish breeding aquarium tool 1 in which Bacillus subtilis were inhabited was added to confirm the reduction of the aquoia. Here, the fish rearing tank tool 1 has a weight of about 140 g. In addition, the fish breeding aquarium tool 1 was prepared by putting about 1 billion bacteria in 1 liter of an aqueous solution and absorbing the aqueous solution containing the bacteria. FIG. 5 (a) shows the state on the second day, and FIG. 5 (b) shows the state on the twelfth day. On the twelfth day, the transparency of the water was greatly increased, and a decrease in the blue sea urchin was confirmed. The experiment was carried out by placing the tip of the air tube under the center of the fish breeding aquarium tool 1 and generating air (bubbles) therefrom.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to this embodiment, A various deformation | transformation is possible within the range as described in a claim.
