The present invention relates to an indoor aquaponics assembly which includes a base, an aquarium positioned above and supported by the base, a planter positioned above the aquarium, an aquarium conduit and a planter conduit. The planter is provided with at least two through holes facing towards the aquarium, one being adapted for a water drainage tube to pass through for draining water from the planter to the aquarium, and one being adapted for a tube of a pump to pass through for pumping water from the aquarium to the planter. The present invention aims at reducing the time and efforts required for caring and maintaining the aquarium and the plants.

The invention relates to a recirculating culture system for cultivating and/or breeding aquatic creatures, comprising: a recirculating system for circulating and controlling the temperature of a fluid, wherein the recirculating system has a culture pool (1) for receiving the fluid, a water reservoir (2) for storing the fluid, a temperature-control device (3) designed to supply thermal energy to and/or remove thermal energy from the fluid, a pump system (4) for circulating the fluid, and a filter system (5) for filtering the fluid; as well as a container (6) having at least one internal space (61), wherein the recirculating system is arranged in the at least one internal space (61) of the container (6).

A device for high density culture of fish larvae includes: a nursery tank, a first aerotube, a standing mesh drain pipe, and a dual-drain recirculating water treatment system. The nursery tank is a rounded corner tank or a polygonal tank without dead corners. The first aerotube is disposed around the bottom of the inner wall of the nursery tank. The standing mesh drain pipe is disposed in the center of the bottom of the nursery tank. The dual-drain recirculating water treatment system includes a first water treatment system and a second water treatment system. The first water treatment system and the second water treatment system are symmetrically disposed on both sides of the nursery tank, respectively. The first water treatment system is configured to purify upper layer water of the nursery tank, and the second water treatment system is configured to purify lower layer water of the nursery tank.

Apparatus (10) for removing gases in a liquid, and/or for removing foam and particles from a liquid and/or for the transport of liquid, the device (10) comprises conduits (16) for transporting the liquid from a first location to a second location, where the conduit (16) comprises a first upstream conduit portion (16a) for receiving of liquid, a substantially horizontal conduit portion (16b), a downstream conduit portion (16c) to discharge liquid out of the conduit (16), and a venting conduit portion (16d) to discharge gases, particles and a part of liquid out of the conduit (16) via conduit portion (16e) and means (17) arranged in the upstream conduit portion (16a) and/or horizontal conduit portion (16b) for supplying microbubbles to the conduit (16), and that in the conduit (16) means (19) are provided for establishing vacuum in parts of the conduit (16), characterized in that the device (10) in the conduit portion (16b) comprises two or more venting conduit portions (16d).

An impeller for use in an aquarium filter pump includes a shaft and a plurality of impeller blades radially extending from the shaft. Each of the impeller blades includes opposite blade faces. A depression is in each of the blade faces and aids in pushing the water. The depression can be a variety of shapes and can have its deepest portion along one of the edges of the blade.

An aquarium filter assembly includes a transfer tube to convey aquarium liquid and a pre-filter member secured to an end of the transfer tube. The pre-filter member may include a rigid porous media basket, or it may include a micron filter of pleated media.
