Having a Mag-Float on hand is as essential for aquarium maintenance as keeping a net and bucket near your aquarium. Scrub away algae without ever getting your hands wet, thanks to its clever magnet-on-magnet design. Simply drag the no-scratch handle, and inside your aquarium, 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.
For all round fishbowl aquarium sizes having a maximum surface thickness of 3/8". Safe on glass or acrylic. Measures 2" diameter x 1-1/2".
