Mag-float Algae magnet, several sizes

Mag-Float produces the well-known and popular algae magnets for your aquarium. The magnet is attached to the glass, and is used easily and simply by running the magnet over the glass - thereby removing algae and dirt from your aquarium. Effective algae magnet for large aquariums with a glass thickness of up to 16 mm. With Mag-Float algae magnets you do not have to pick up the algae magnet from the bottom of your aquarium if it falls off, because the inner part is floating and can be easily caught again on the water surface. Available in mini, small, medium and Extra large.
