ABSTRACT:
An aquarium pump including a first unit comprising a magnet in an encasement disposed against the outside panel of an aquarium or other tank, and a second, submersible unit comprising a magnet in an encasement and a motor, an impeller, and buoyant material contained within a chamber disposed against the inside panel of an aquarium or other tank and opposing the first unit. The magnet included on the second, submersible unit includes a plurality of recesses into which are inserted synthetically coated ball bearings that are allowed rotate freely, with a portion of the ball bearings extending outside the magnet thus allowing the ball bearings to make contact with the aquarium or tank wall and allowing the second, submersible unit to be maneuvered into place without the necessity of violating the aquatic environment. The buoyant material allows the second, submersible unit to remain fixed in place solely utilizing magnetic attraction.
