Abstract
An automatic cleaning aquarium has a top aquatic section (1) with vertical walls (2) and a bottom waste section (3) having tapered walls (4) which funnel to a valved flushing orifice (5). A grate-supported screen (8, 9) separates the top aquatic section from the bottom waste section. The valved flushing orifice and a discharge conveyance (11) are large enough to permit effectively fast flushing of the grate-supported screen and the tapered walls of the bottom waste section. Positioning of the valved flushing orifice can be designed for various sizes and uses of the aquariums. Air for aeration and circulation of water in the aquarium is supplied centrally or optionally through an aeration pipe (17) extended near end-to-end and having a plurality of aeration orifices (20). A water tap or a pail with suitable water can be used to refill the top aquatic section after flushing.
