The Mag-Float 20 simplifies terrarium and aquarium maintenance like never before! Its clever magnet-on-magnet design lets you scrub away algae and other deposits without getting your hands wet. Simply drag the no-scratch handle from the outside; inside your aquarium, the scrubber follows, cleaning as it goes. And if the magnets separate, the scrubber floats to the surface, so you'll never have to dig around on the bottom.
For all round terrariums and aquariums with a maximum surface thickness of 3/8". Safe for glass or acrylic. Measures 2" diameter x 1-1/2".
