Mag-Float®Medium Glass Aquarium Cleaner
Simply drag the no scratch felt-lined exterior magnet, now featuring an easy-grip ergonomic design, and the interior (wet side) magnet follows. Scrub and scrape away film, algae and mineral buildup to clean and restore aquarium views with greater ease and efficiency. Best of all, if the magnets separate, the interior magnet floats right back to the surface, so you will never have to dig around on the bottom.
Mag-Float Glass Aquarium Cleaner measures approximately 3-1/4" x 2-1/2" x 1" high. Recommend to be used on glass aquariums up to 350 gallons with up to 5/8" surface thickness.
