Algae Magnets come in two parts. Both contain magnets : one half of set has coarse algae removal material on its face, and the other has a soft non-scratch material. The coarse faced magnet is placed on the inside of the aquarium glass, with the soft faced magnet on the outside. Moving the outside one across the face of the glass drags the inner magnet with it, thereby removing the algae from the inside glass as it moves. For glass up to 16mm thickness Easy removal of algae from glass/acrylic surfaces No longer knock over decorations, damage corals and invertebrates No longer get your hands submerged into the water of the fish tank Time/money saver on maintenance Large cleaning surface area makes the job quick and efficient Stays free of debris Can be maintained attached to aquarium surface Strong, high-quality neodymium rare earth magnets Available for glass and acrylic aquariums Can be used on freshwater and saltwater tanks Magnet does not lose strength over time Easy retrieval of inner magnet
