Mag-Float

The easiest way to clean algae!
Having a MagFloat on hand is as essential for aquarium maintenance as keeping a net and bucket near your tank. Scrub away algae without ever getting your hands wet thanks to its clever magnet-on-magnet design. Simply drag the no-scratch, felt-lined handle, and inside your tank, the scrubber follows, cleaning as it goes. Better yet, if the magnets separate, the scrubber floats right back to the surface, so you'll never have to dig around on the bottom.

Tips
Because you never have to reach into the aquarium, Mag Floats prevent toxic lotions or soap residue on your skin from getting in your aquarium. They keep your hands dry, and you don't ever have to worry about losing the scraper on the bottom because it floats when not attached to the magnet through the glass
