The present disclosure relates to the technical field of aquarium equipment. Disclosed is an aquarium that includes a tank, an electric device disposed in the tank, a first conductive contact configured to be coupled to an external power source, and a second conductive contact coupled to the electric device. The first conductive contact is configured to come into contact with the second conductive contact to power up the electric device.

An automatic aquarium system that uses an automatic aquarium siphon bridge comprises a first water tank and a second water tank. The system further comprises a siphon bridge arranged between the first water tank and the second water tank. The system also comprises a pump arranged in one leg of the bridge. The aquarium system also comprises a cross over siphon arranged within the siphon bridge wherein one end of the cross over siphon is connected to an inlet of the pump and the opposite end is arranged in the second water tank. The automatic aquarium system may also comprise an air extraction siphon arranged between a top surface of the bridge and the inlet of the pump. This may allow for clean well aerated water to circulate throughout the automatic aquarium system, i.e., between the first and second tank via the bridge to allow for fish to properly enjoy two tanks and the bridge area therebetween.

The invention relates to a wire material consisting of metallic material having an oxide surface, wherein the oxide surface of the wire material has a first oxide layer, which covers the metallic material at least in part and has a thickness of at least 200 nm to 2 μm, and the oxide surface of the wire material has a second oxide layer which covers metallic material in the regions which are not covered by the first oxide layer. According to the invention, the second oxide layer has a maximum thickness of 0.01 to 10% of the thickness of the first oxide layer. The invention furthermore relates to a mesh and a breeding cage for aquaculture.

Disclosed is an aquarium that includes a tank, a magnetic induction transmission apparatus, and a first electric equipment disposed in the tank. The magnetic induction transmission apparatus includes a driving module and a receiving module. The driving module is disposed outside the tank and adjacent to a tank wall of the tank and is configured to be separable from the tank, and the receiving module is disposed on the tank wall of the tank and disposed corresponding to a position of the driving module. The driving module is connected to an external power source. The receiving module is connected to the first electric equipment and is operative to generate an induced current when the driving module is powered on.

Provided is an aquarium that includes a tank, a magnetic induction driving module, a magnetic induction power generation module, and an electric device disposed in the tank. The magnetic induction driving module is disposed outside the tank. The magnetic induction power generation module is disposed inside the tank adjacent to the magnetic induction driving module. The magnetic induction driving module is coupled to an external power source. The magnetic induction power generation module includes a magnetic induction generator, which includes a rotor assembly and a power generation induction coil which is wound around an exterior of the rotor assembly and which is coupled to the electric device. When the magnetic induction driving module is powered on, the rotor assembly is operative to rotate relative to the power generation induction coil, enabling the power generation induction coil to generate an induced current to power up the electric device.

Aquatic structures with adjustable buoyancy constructed in part with a vent valve for a buoyancy control device suitable for divers, where the vent valve may be opened by any combination of over-pressure, manual pressure relief or a powered means, where a force to a valve plug is applied by means of a spring that is constrained to prevent entirely lateral and angular movement but in which movement of the plug in the axis of the seat is unconstrained.

An aquaculture system including a fish tank, a floating media bioclarifier, and a mineralization tank. The mineralization tank includes a first influent inlet for receiving sludge having a first solids concentration from the bioclarifier, an effluent outlet for returning to the bioclarifier a fluid having a second solids concentration less than the first solids concentration, and a second influent inlet configured to receive influent from the fish tank which has bypassed the bioclarifier. A hydroponic system is configured to receive effluent from the bioclarifier.

The present application is directed to a method of applying a plant growing material to a surface of a mold décor, the method comprising flocking at least one aquatic seed to the surface of a mold décor to adhere the at least one aquatic seed to the surface of the mold décor.
