Mag Float's magnetic cleaners are unique, effective and easy to use. As they float, they can be easily maneuvered, cleaning corners without sinking. The cleaning brush will not scratch your acrylic tank as sand and gravel will not adhere to it, and the magnets remove algae without effort.
Simply clean the outside aquarium surface thoroughly and remove any debris from the Mag Float before each use. The side with the logo attaches to the outside surface and the Mag Float can be left attached to the outside surface between uses.
For use with freshwater and saltwater aquariums, acrylic only.
Caution: It is a strong magnet, watch your fingers.
