Abstract: A submersible, water circulation system for enclosed tanks such as used by municipalities, fire districts, and industries. The system includes a driving unit having a shell extending along an axis with a pump supported within the shell. The shell has at least one inlet and at least one outlet and is positionable on the floor of the tank with the outlet facing upwardly. The upwardly facing outlet is preferably a thin, upwardly facing, elongated slot and creates a thin, substantially planar discharge of water therethrough that is directed upwardly toward the surface of the body of water. The substantially planar discharge presents a very large surface area for its volume and induces water adjacent the outside of the shell of the driving unit to move upwardly with it toward the surface of the body of water.

Abstract: A watering device for animals with continuously flowing water to attract the attention of the animal utilizes a water screw device within the watering device to move water from a lower bowl of the device to an upper bowl to create flowing water. The water screw is configured such that the electrical components of the water screw remain separated from the water of the watering dish to remove the possibility of electrocution of the water. Rather, only the mechanical components of the water screw device contact the water of the watering device while the electrical motor of the water screw remains safely out of the water.

Abstract: An aquarium system for containing water and aquatic life therein is disclosed that includes a reservoir and an aquarium that is mounted generally above the reservoir. The aquarium has an outlet in liquid communication with the reservoir through an outlet conduit that includes a discharge mechanism, preferably an inverted U-shaped siphon conduit, that periodically discharges a portion of the water from the aquarium to the reservoir therethrough once the water has reached a maximum water level. A pumping mechanism pumps water from the reservoir up to the aquarium through an inlet conduit that is in fluid communication with the reservoir and an inlet of the aquarium. As such, when the water reaches the maximum level in the aquarium, the siphon conduit substantially fills with water which begins to flow out through the outlet conduit, drawing a portion of water from the aquarium rapidly through the outlet conduit until the water in the aquarium reaches the open bottom end of the siphon conduit.

Abstract: By adding an evacuated vertical structure onto a body of water where part of the structure extends above the body of water, the water level rises into the structure because of the vacuum. Use of the structure increases the overall volume of water in an aquarium and provides added space for fish as well as enhanced viewing of the aquarium.

Abstract: A holder (4) for retaining an aerator conduit (5) for placement on the bottom (6) of an aquarium tank (1). The holder has a trough with at least one side wall (11a,b) and a retaining means, such as channel (12), in the trough. The holder may be supported in an upright position on the bottom of the aquarium tank by sand and gravel pressing against the outside surface of its side walls. Side walls further keep sand and gravel from covering the aerator conduit. A stabilizer base (14) may be provided on the bottom of the holder. The aerator holder provides for more evenly distributed air bubbles (2) in the aquarium and thus better oxygenation of the water for the fish contained therein. Preferably the holder is made of clear plastic so that it is virtually invisible to an observer, thereby providing an overall more aesthetic appearance for the aquarium.

Abstract: An aquatic habitat extension device uses a circulation assembly to reversibly maintain a volume of water above the surface of an underlying body of water. The aquatic extension can be used alone or with other similar aquatic habitat extensions that themselves can be varied in terms of size, shape, and the degree to which they are filled with water. Each habitat extension has a water inlet located beneath the surface of a body of water, which preserves the partial vacuum in the aquatic extension, and provides an entryway for aquatic animals to enter the transparent habitat extension where they are observed. To increase the occasions when fish or other aquatic animals enter a given habitat, a food delivery system delivers food to an air pocket trapped in the upper portion of an individual extension. Illuminating or tinting the habitats enhances the beauty of an aquarium, pond, water garden, or other body of water and can be accomplished through the use of a fiber optic cable system or more conventional means.

Abstract: An aquarium pumping system includes: a container having a pump installed in the container and having sand filled in the container, a discharge tube connected between the container and an aquarium for delivering water into the aquarium, a suction tube connected between an aquarium and a suction port of the pump with the suction tube having an inlet aperture formed in the suction tube and constantly submerged in the container under a water level within the container to obtain an enough net positive suction head (NPSH) of the pump, and a gas tube connected to the container for supplying carbon dioxide gas into the container to react with calcium carbonate in the sand to form calcium ions which will be dissociated into the water delivered into the aquarium for raising fish, coral or other animals in the aquarium.

Abstract: An aquarium system is provided for displaying marine life. The aquarium includes a reservoir for receiving water therein, the water in the reservoir defines a reservoir water level. A tank is positioned above the reservoir also for receiving water therein. The water in the tank defines a tank water level such that the reservoir water level is below the tank water level. A fish display tube provides a habitat for the marine life and has first and second ends communicating with the water in the tank. A return tube includes a first end coupled to and communicating with the fish display tube, and a second end communicating with the reservoir such that a syphon on the second end of the return tube draws water from the tank, through the fish display tube and the return tube, into the reservoir. Means are provided for pumping water from the reservoir into the tank to prevent the overflow of water in the reservoir.

Abstract: A sea current generator aquarium including an air-tight water chamber located at one end of the aquarium with an opening into the aquarium extending across the bottom of the chamber. A constant flow air pump connected to the top of the water chamber for pumping air therein and expelling water therefrom out of said opening into the aquarium and an air valve positioned in an duct connecting the top of the water chamber to atmosphere in an actuating means for cycling the air valve from an opened to a closed position whereby in its opened position, the air valve and duct exceed the capacity of the pump and allow the elevated water column in the aquarium to move back into the water chamber through said opening until the water level is stabilized and thereby creating a back and forth current of water within the bottom regions of the aquarium.

Abstract: An apparatus for use with an existing aquarium tank for extending the aquarium tank includes an extension tank having opposite side walls, a top wall, an open bottom, an interior chamber and a shoulder between the top wall and the bottom wall for supported engagement on the top of the aquarium tank. An exhaust valve assembly includes a one way air valve, a float valve and a valve seat structured and disposed to permit one way passage of air therethrough in response to an external vacuum force, causing air to be drawn from within the interior chamber of extension tank. The apparatus further includes a sealed pump box with an air pump therein to create a vacuum force for drawing air from within the interior chamber and an aeration assembly for replenishing air to the extension tank.

Abstract: An aquarium includes a lower hollow body which defines a lower chamber and an upper hollow body which defines an upper chamber. A mount plate is removably mounted in a bottom of the lower chamber and a waterproof housing is provided on the mount plate to receive a pump therein. The upper hollow body includes a plate and a housing projecting upward from the plate to define the upper chamber. A water inlet is formed in the plate beyond the housing, through which water is inputted into the lower chamber. An air passage is formed in an upper wall of the housing. A float is movably provided to the housing to block the air passage for isolating the upper chamber unless the float is raised. A protrusion projects upward from the upper wall of the housing, defining a cavity above the upper chamber. An inlet pipe has a lower end attached to the pump and an upper end extending into the cavity defined by the protrusion, preventing water from entering into the inlet pipe.
