ABSTRACT:
A system and method for removing waste and debris from an aquarium tank and from the water supply therein without having to empty the tank or remove the fish therefrom. The apparatus comprises a movable cleaning means positioned adjacent the bottom surface of the tank, means for expelling waste and debris from adjacent the bottom surface of the tank and means for moving the cleaning means along the bottom surface of the tank so that the movable cleaning means dislodges waste and debris deposited thereon and directs the dislodged waste and debris generally toward the expelling means to be expelled thereby. The cleaning means preferably comprises a barrier structure having a metallic element incorporated therein, and the moving means preferably comprises a magnetic source, such as a hand-held permanent magnet, positioned externally of the tank beneath the underside thereof to move the barrier structure along the bottom surface by magnetic attraction. The expelling means preferably includes a water directing means for drawing water having dislodged waste and debris upwardly from adjacent the bottom surface of the tank. The drawn water may be filtered and returned to the aquarium or disposed of and replaced with fresh water.
