An apparatus for dispensing food to an aquarium includes a reservoir, a pump, and a draw line coupled between the reservoir and the pump to draw solution from the reservoir and pass the solution downstream to the pump. The draw line is routed through the pump. A supply line and return line are respectively configured to supply and return water from and to the aquarium. A mixing connection is downstream from the pump and couples the draw line with the supply and return lines. The reservoir, pump, draw line, supply line, return line, and mixing connection are all contained within a refrigerated compartment to keep the aquarium food from spoiling.

A fluid pump assembly is provided. The pump has a pair of units magnetically coupled to each other. The first unit contains a drive motor and a magnetic assembly. The second unit contains a magnetic assembly and a blade of a propeller/impeller for imparting movement to a fluid. As the first unit is activated by the drive motor, a magnetic flux is created which in turn rotates the magnetic assembly in the second unit, driving the blade.

The present invention relates to fluid pump assemblies in general, and in exemplary embodiments to fluid pump assemblies that are magnetically supported in position, and to related kits and methods useful to circulate water in aquariums. The fluid pump assembly comprises an outer mount, an inner mount, and a pump. The outer mount includes at least one outer permanent magnet; the inner mount includes at least one inner permanent magnet; and the pump includes at least one soft magnetic material. The outer permanent magnet, the inner permanent magnet, and the soft magnetic material collectively form a magnetic circuit.

There is provided processes and uses of an inline saturator for maintaining fish in a cage in an open body of water, the process comprising: restricting movement of water into and out of a part of the cage and forming a portion of water within the part of the cage. The process also includes injecting oxygenated water produced by an inline saturator into the portion of water to raise a dissolved oxygen level and to lower a dissolved nitrogen gas level therein. A treatment process is also provided that includes the steps noted above and further including introducing a medicinal substance into the oxygenated water or the portion of the body of water.

A metering unit for the controlled supply of a substance inside an aquarium tank comprises a containment box and a dosimetric pump which is actuated by an electric motor, both being associated with the containment box. The containment box has at least a first connection element and at least a second connection element which is suitable for being connected to a corresponding first connection element of an additional similar metering unit.

A fully air-powered, n-way redundant aquaponic system for integrated cultivation of various fish, plant, and mushroom species, off-grid, with each grow bed including a respective DC air pump, solar panel, and battery to ensure self-sufficiency, redundancy, and enhanced resilience. Each mushroom grow bed also includes an evaporative cooling system for year-round mushroom production.

An aquaculture system (10) comprising growing modules (GM) and liquid treatment modules (LTM). Each growing module is associated via a network of pipes (101, 201, 202) with a respective liquid treatment module to form a pair (161, 162), wherein if liquid flow through a given pair (161, 162) is stopped and left to settle, liquid within the given pair (161, 162) is arranged to balance out to the same level.

The present invention discloses a recirculating aquaculture system (RAS) and method for shrimp culture through SBR wastewater treatment. The RAS includes a control cabinet, culture tanks, a clean water tank, a clean water filling pipeline, a drainage pipeline, a buried activated sludge tank and a solid-liquid separation mechanism. The solid-liquid separation mechanism comprises a sludge pump, an input pipe, a plate and frame type filter press and a liquid output pipe. An input end of the sludge pump is immersed in sewage of the buried activated sludge tank; and a clean water output end of the plate and frame type filter press is connected with the buried activated sludge tank through the liquid output pipe.

A sterilizer for an aquarium includes a pump for sucking water in an aquarium and a filtering member for filtering the water. The pump includes an inlet from which the water in the aquarium is sucked. The filtering member is connected to the underside of the pump and includes an outlet through which the filtered water flows back into the aquarium. Multiple reflectors are connected to the periphery of the filtering member, and a coat is mounted to outside of the filtering member and covers the reflectors. Multiple ultraviolet sterilizer bulbs are located in the filtering member so as to treat the water sucked from the pump. A cotton sleeve is mounted to the pump and located around the inlet to remove debris and grease.

A pump system includes a submersible pump and a filter. The pump has a housing, an intake, and a discharge. The filter includes a filter housing that releasably engages the pump and that overlies the intake of the pump. The filter housing has an intake, an outlet located between the intake of the filter housing and the intake of the pump. A filter chamber is located upstream of the outlet of the filter housing and is configured to receive filter media. The outlet of the filter housing is disposed inline with the intake of the pump. The coupling may comprise a latch that clips or snaps onto part of the pump, releasably attaching the filter housing to the pump. The latch may engage with opposite sides of the pump when releasably attaching the filter housing to the pump. The latch may include a plurality of spaced apart snaps that snap onto the pump.
