Device for treating internal walls of aquatic basins includes at least one suction cup head, a mobility assembly by means of which it is possible to move the suction cup head along a wall that is to be treated, the mobility assembly including a traveler having motorized wheels that can be oriented according to two unique rolling positions, these two positions being at 90 degrees to one another.

There is a modular, insulated, all-in-one, plug-and-play (MIAP) aquaponics unit that includes a framework having a single base and plural walls; an aquaculture tank defined by a first portion of the single base and a first set of the plural walls; a clarifier tank defined by a second portion of the single base and a second set of the plural walls; a bio-reactor tank defined by a third portion of the single base and a third set of the plural walls; a hydroponics tank defined by a fourth portion of the single base and a fourth set of the plural walls; and piping extending through the plural walls between each two adjacent tanks for allowing water from the aquaculture tank to flow into the clarifier tank and then into the bio-reactor tank and then into the hydroponics tank and back to the aquaculture tank.

Magnetic rotating cleaning apparatuses for cleaning of aquarium walls are shown and described. Each of the cleaning apparatuses includes a first magnetic assembly disposed on an outer surface of the aquarium wall, the first magnetic assembly having an anti-friction pad fixedly attached to a first end of the first magnetic assembly, and a second magnetic assembly disposed on an inner surface of the aquarium wall, the second magnetic assembly magnetically paired to the first magnetic assembly, the second magnetic assembly having a scouring pad fixedly attached to a surface of the second magnetic assembly, the scouring pad making surface-to-surface contact with the inner surface of the aquarium wall. Rotation of a rotation mechanism drives rotation of the first magnetic assembly, rotation of the first magnetic assembly causing synchronistic rotation of the second magnetic assembly. In some examples, the scouring pad has at least one opening configured to reduce surface-to-surface contact between the scouring pad and the inner surface of the aquarium wall, and to collect debris from the inner surface of the aquarium wall and reduce friction during rotation.

Submersible isolation enclosure apparatus constructed of flexible, water resistant to water proof fabric or sheeting for enclosing and isolating selected areas of water bottom and water volume from surrounding water with access to the isolated bottom area exposed within a Base Member through one or more closed wall, tubular Access Member(s) connected to the Base Member and accessible from the water surface. Center-radial and perimeter portions of the Base Member fitted with attachment points and one or more tubular, closed wall Sleeve Members to allow for use of floatation, internal supporting rods or piping, and weights, to assist in the movement, positioning, shaping and securing of the apparatus to the selected water bottom area. Flexible fabric and weighting system allows the lower perimeter of the Base Member to conform to bottom structure.
