Mag-Float Floating Magnet Glass & Acrylic Aquarium Cleaner - Mini
The Mag Float ’s powerful rare earth neodymium magnets provide a lifetime durability and ample strength to get the job done. Simply move the outside magnet that contains the felt, and the inside abrasive velcro magnet scrubber follows, cleaning as it goes. If the magnets separate, the inner magnet floats right back to the surface, so you'll never have to dig around on the bottom. This prevents the magnet from picking up any debris and causing scratches on your tank.
Recommend to be used on aquariums up to 10 gallons, with a surface thickness up to 3/16”
Product dimensions: (1 ¾” x 15/16” x ¾”)
