  • the invention relates to improvements in marine aquariums having an aquarium housing divided into a leading aquarium inhabitant compartment for accommodating aquarium inhabitants and a trailing filtration compartment for filtering aquarium water and returning filtered aquarium water to the aquarium inhabitant compartment.
  • Some marine aquariums have an aquarium housing divided into a leading aquarium inhabitant compartment for accommodating aquarium inhabitants and a trailing filtration compartment for filtering aquarium water and returning filtered aquarium water to the aquarium inhabitant compartment.
  • Marine aquariums include biological, chemical and mechanical multi-stage water filtering arrangements to maintain aquarium water at required levels of water quality.
  • a filtration compartment can accommodate either a rear sump arrangement or a water piping arrangement for flow communication with an in-cabinet sump arrangement.
  • the water piping arrangement preferably includes a regulated down flow pipe and a return pipe for returning filtered water to the aquarium inhabitant compartment.
  • Marine aquariums suffer from evaporation loss of aquarium water and require periodic top up to maintain a minimum water level.
  • Water filtering arrangements require considerable routine maintenance activities by aquarists to maintain aquarium water at a required water quality and therefore marine aquariums preferably afford convenient aquarist access thereto. But water filtering arrangements are unsightly and reduce the enjoyment of viewing aquarium inhabitants.
  • Some aquarium housing partitions extend above an uppermost aquarium top rim to conceal a trailing filtration compartment therebehind from a front view facing the marine aquarium.
  • Marine aquariums can be generally classified into two sizes depending on aquarium volume. Marine aquariums having up to 150 liter aquarium volumes are regarded as so-called small marine aquariums. Small marine aquariums employ a rear sump arrangement due to size and cost constraints. Due to limited space available in small marine aquariums, their multi-stage filtration systems are typically insufficient to maintain a required water quality. Moreover, they forego automatic float-operated top up reservoirs which can lead to insufficient water level to the detriment of the wellbeing of aquarium inhabitants.
  • In-cabinet sump arrangements can include larger water filter components than rear sump arrangements. Moreover, additional water filter components can be readily added to in-cabinet sump arrangements because of additional available cabinet space which is precluded from rear sump arrangements.
  • Some aquarists purchase marine aquariums with rear sump arrangements and wish to upgrade to in-cabinet sump arrangements.
  • a retrofit upgrade from a rear sump arrangement to an in-cabinet sump arrangement includes inter alia emptying a marine aquarium, drilling holes in its glass base for a water piping arrangement, and other cumbersome and problematic tasks. Accordingly, a retrofit upgrade from a rear sump arrangement to an in-cabinet sump arrangement is considered impractical.
  • the present invention is directed towards improvements in marine aquariums having an aquarium housing divided into a leading aquarium inhabitant compartment for accommodating aquarium inhabitants and a trailing filtration compartment for filtering aquarium water and returning filtered aquarium water to the aquarium inhabitant compartment.
  • One improvement includes provisioning a discrete filtration compartment screen for manual mounting on an aquarium top rim above an aquarium housing partition in an upright concealing position to conceal a filtration compartment therebehind from a front view facing the marine aquarium.
  • the filtration compartment screen is supplied as a separate component from a marine aquarium thereby not increasing the height of packaging containing a marine aquarium for storage and transportation purposes. Also, supplying the filtration compartment screen as a separate component precludes its damage during transportation.
  • the filtration compartment screen is preferably pivotal mounted on an aquarium top rim so as to be readily manually disposed between its upright concealing position and a forward folded access position for affording aquarist access to a filtration compartment for routine maintenance activities.
  • the filtration compartment screen can be equally added to both a marine aquarium with a rear sump arrangement or an in-cabinet sump arrangement.
  • Another improvement relates to so-called small marine aquariums and provisioning a filtration compartment compactly housing a multi-stage water filtering arrangement and an automatic float-operated top up reservoir while affording convenient aquarist access to same for routine maintenance activities of the water filtering arrangement and routine filling of the automatic float-operated top up reservoir.
  • the filtration compartment includes a central protein skimmer, a micron filter bag on one side of the protein skimmer and an automatic float- operated top up reservoir on the other side of the protein skimmer.
  • the small marine aquariums can be optionally fitted with a discrete filtration compartment screen.
  • a marine aquarium having a filtration compartment for use with either a rear sump arrangement or an in-cabinet sump arrangement.
  • the marine aquarium is envisaged to be initially used with a rear sump arrangement and subsequently undergo a retrofit upgrade for use with an in- cabinet sump arrangement by having to drain only the filtration compartment and not the entire marine aquarium.
  • the filtration compartment is pre-formed with at least two throughgoing apertures in its base and fitted with a bulkhead arrangement including plugs for plugging the throughgoing apertures.
  • the marine aquarium can be optionally fitted with a discrete filtration compartment screen.

Abstract

La présente invention concerne des perfectionnements apportés à des aquariums marins présentant un logement d'aquarium divisé en un compartiment avant pour habitants d'aquarium et un compartiment arrière pour filtration. Un perfectionnement consiste à fournir un écran de compartiment de filtration distinct destiné à être monté dans une position verticale de dissimulation pour dissimuler le compartiment de filtration derrière depuis une vue de face orientée vers l'aquarium marin. Un autre perfectionnement consiste à proposer un compartiment de filtration avec un agencement de filtration d'eau amélioré et un réservoir à remplissage à flot pour petits aquariums marins. Un autre perfectionnement consiste à proposer un agencement de cloison dans un compartiment de filtration pour permettre à un aquarium marin de subir facilement une mise à niveau d'un agencement de siphon arrière initial à un agencement de siphon dans l'armoire.
