A light system for an aquarium includes an aquarium tank and a lid covering the open top of the tank. The lid is pivotably attached to the tank and is pivotable between a covered position and uncovered position. A light source is secured to an interior portion of the lid and moves with the lid between the covered position and uncovered position. The light source emits a. light beam. An alignment arrangement is provided for the light source and is constructed and arranged to ensure the light beam projects into the tank interior volume regardless of the position of the lid and light source.

An autonomous water quality sensing apparatus, a system and a method for operating the apparatus are provided. In the autonomous water quality sensing system, the autonomous water quality sensing apparatus is configured to move on a track. In the method, a driving mechanism is used to drive the autonomous water quality sensing apparatus to operate over an elevated track surrounding one or more pools. The autonomous water quality sensing apparatus includes a sensing device. The sensor is put into the pool at a planned stop by a sensor deploying mechanism of the autonomous water quality sensing apparatus, so as to obtain water quality data of each of the pools according to a routing plan and a length setting.

An adjustable locking fastener comprising a post and a lever for use in an aquarium. The adjustable locking fastener includes a post, a lever and a letoff portion. The adjustable locking fastener may be quickly removed and reattached with minimal effort, and with a constant set point for the attachment.

A coral mounting apparatus that facilitates mounting a live coral or other decoration to rock in an aquarium comprising a coral mount; a dock that is slidably receivable within the coral mount; and a docking mechanism that enables the dock to slide in and towards with respect to the coral mount upon docking, and away and slide out with respect to the coral mount upon undocking.

The present invention relates to an aquarium pressurized gas vessel for supplying an aquarium (12) with CO2 gas generated in the aquarium pressurized gas vessel (10), wherein the aquarium pressurized gas vessel (10) comprises: a receiving vessel (14) for receiving a nutrient substrate and a reactant interacting with the nutrient substrate such that the nutrient substrate and the reactant react with each other to generate CO2 gas; a closing device (16) for closing the receiving vessel (14) in a pressure-tight manner; a gas outflow device (18) for extracting CO2 gas from the aquarium pressurized gas vessel (10) for the aquarium (12), wherein the CO2 gas has a gassing pressure (p_B) when flowing into the gas outflow device (18); a gas vessel pressure regulator (20) for adjusting a gas vessel pressure (p_G) which substantially corresponds to the gassing pressure (p_B).

Further, the present invention relates to a CO2 gassing system (28) comprising the aforementioned aquarium pressurized gas vessel (10).

Provided is a circulating aquaculture facility for saltwater ponds. The circulating aquaculture facility comprises a cultivation tank, a division plate vertically arranged in the cultivation tank to divide an inner cavity of the cultivation tank into a left inner chamber and a right inner chamber; a water inlet pipeline, water in the water inlet pipeline enters the cultivation tank through the left rectangular through hole of the cultivation tank; an outlet pipeline, sewage discharged from the right rectangular through hole of the cultivation tank is capable of entering the outlet pipeline; and an oxygen supply device which delivers oxygen to the inner bottom of the cultivation tank.

Disclosed are livewell systems and methods of operating livewell systems. A livewell system may include a livewell tank having a chamber formed therein, a fill sensor configured to detect a fill level of the chamber, an intake pump configured to selectively convey water into the chamber, and a control unit including a processor and a memory storing instructions. The processor may be configured to execute the instructions to receive a fill signal, determine whether the chamber is filled to a predetermined fill level; and in response to the fill signal and a determination that the chamber is not filled to the predetermined fill level, cause the intake pump to convey water into the chamber.

A method of drawing aquatic or other animal life in a fish-style tank to a clear side of the tank by providing a shelter structure affixed to an interior wall of the tank that encourages that life to enter by offering protection. The shelter structure does not obstruct people from viewing the fish from outside the tank. Treatments to the walls of the shelter can alter the opacity, color, appearance, shape and other aspects to increase the attractiveness of the shelter to the fish (or other animal), affect the behavior of the fish and provide ornamentation.

An aquarium having an adjustable lighting system for enhancing the display of fluorescent objects, such as fluorescent fish, contained within the aquarium under various external lighting conditions, such as a dark room or a brightly lit room. The aquarium comprises a tank and a plurality of light sources. Each light source emits light at a different wavelength spectrum which is selected to enhance the display of the fluorescent object under each type of external lighting condition. An electronic control is provided to control the operation of the plurality of light sources such that each light source may be selectively turned on/off based on the external lighting condition, or chronological criteria, to provide the best viewing experience.

A stand for a vivarium has a side wall with a cutout and at least one first magnet closure element arranged adjacent to the cutout. At least one cover is provided that is to be inserted into the cutout and at least partially covers the cutout in an installed position of the at least one cover in the cutout. The at least one cover has at least one second magnet closure element that in the installed position is arranged so as to correspond with the at least one first magnet closure element so that the at least one cover is secured in the cutout exclusively by magnetic forces interacting between the at least one first magnet closure element and the at least one second magnet closure element in the installed position.
