High density housing for aquatic animals
First Claim
1. An aquarium system, comprising:
- a tank having an inside bottom sloping to at least one point of lowest elevation;
a water supply to the tank;
a water drain from the tank, the water drain having a drain inlet at said point of lowest elevation, whereby sediment is drawn into the drain inlet, wherein the tank has inside walls sloping to an elongated trough in the inside bottom;
a support for the tank positioned to tilt the elongated trough downwardly to one end thereof, and wherein said point of lowest elevation is at said end of the trough;
wherein the trough is substantially parallel to a supporting surface for the tank and the support includes a rack having tilting supports for engaging said supporting surface to support the tank.

Abstract
A housing system for aquatic animals has a shelf-like rack holding tiers of individual tanks or aquariums (aquaria), each removably suspended from structural members that engage flanges of the tanks. The tanks are tilted inwardly of the rack and have covers with fittings on the higher or outer side, that intercept flow between a supply and a drain to inlet water when the tank is in the rack and to recycle the water at any tank position that is unoccupied. The inside bottom of each tank is contoured, for example with a longitudinal trough, so sediment collects at a low spot on the lower or inner side, where a drain inlet is placed to provide a drainage outlet that opens at a velocity increasing restriction at which sediment is entrained. The drain has a spring biased valve that opens the drain only when the tank is fully inserted in the rack. Water supply, water drain and air supply conduits are integrated using an extrusion or multiple passage conduit for air supply, water supply and water return at the interception point of the tank water inlet. The housing system is apt for zebrafish for laboratory experimentation.

5. An aquarium system, comprising:
-
a tank removably received in a support;
a water supply for the tank when in the support; and
at least one a water drain from the tank when in the support;
wherein the water supply comprises a flow path along which feed water flows along at least one path between a water purifying device and a waste water collection conduit, further comprising a supply inlet to the tank positioned to intercept the feed water flowing along the at least one path when the tank is carried on said support, and wherein the feed water flows directly to the waste water collection conduit when the tank is removed from said support. - View Dependent Claims (6, 7)

8. A re-circulating water system for continuously supplying filtered water through a plurality of aquarium tanks, comprising:
- a water return header, a filter system, flow control means, and a water supply header connected in series, wherein said water supply header includes multiple branches each disposed in fluid communication with at least one water supply line, each of said branches running to a water inlet for one of said aquarium tanks, wherein at least one of said water return lines runs from an outlet on said aquarium tank into said water return header, and further wherein said utility apparatus is constructed such that water flows directly from said water inlet into said water outlet when no aquaria are present in said re-circulating water system.

11. A high density housing for aquatic life comprising:
-
a plurality of aquariums, each of said aquariums comprising a tank and a cover, each of said tanks comprises a bottom forming a trough to a lowest point within said tank, and wherein each said tanks further comprises a sump positioned adjacent to a bracket on an end wall of said tank, wherein said sump comprises a dip tube extending into said tank and a valve for selectively preventing water discharge from said tank and said bracket comprises a grommet disposed above a drain, wherein said valve opens when said aquarium is inserted in a rack such that water can exit through said drain; and
said cover comprises a raised portion having an access opening with flow diversion means extending at an angle away from said access opening, and wherein each aquarium is adapted to be placed in said rack;
said rack comprising vertical support members connected perpendicularly to horizontal support members, wherein each horizontal support member has multiple tank suspension arms extending away from said horizontal support member at an upward angle, such that when each of said aquaria is received in said rack, said aquaria are suspended at an angle, and wherein each tank suspension arm has a utility apparatus comprising a water inlet, an air inlet, and a water outlet, wherein said water inlet is located above said air inlet and said air inlet is located above said water outlet; and
said water outlet runs into said water return line;
a re-circulating water system comprising a water return header, a filter system, flow control means, and a water supply header connected in a series configuration, wherein said water supply header feeds multiple water supply lines, each of said water supply lines running to said water inlet in one of said utility apparatus, and each of said water return lines running from said outlet on each of said utility apparatus into said water return header; and
said flow diversion means in said cover protrudes into said utility apparatus and intercepts water from said water inlet and diverts it into said tank before said water can exit through said water outlet when one of said aquaria is placed in said rack, and wherein water exits each of said tanks into said water return lines through said drains in said brackets via said sump apparatus adjacent to said brackets. - View Dependent Claims (12, 13, 14, 15)

16. An aquarium system for a plurality of tanks, comprising:
-
a supporting rack;
a water supply having a water supply header and a water return header carried on the rack;
wherein the rack has supporting surfaces that removably receive the tanks at positions in which the tanks receive water from the water supply header and drain water to a water return conduit, water outlets being provided on each tank and defining a water level in the tank when in the rack, the tanks being supportable apart from the rack with the water level at a lower elevation than the water level when in the rack at least at one part of the tanks. - View Dependent Claims (17, 18)

19. An aquarium system for a plurality of tanks, comprising:
-
a rack for removably supporting the tanks, the rack being coupled to a recirculating water supply comprising a water supply header, a water return header associated with the water supply header, and a drain spaced from and placed lower than the water return header;
wherein the tanks occupy positions in the rack at which the tanks intercept a flow of water from the water supply header to the water return header and discharge into the drain, and wherein the flow of water proceeds directly from the water supply header to the water return header at positions that are not occupied by the tanks. - View Dependent Claims (20)
