Mag-Float Acrylic Aquarium Cleaner, Small

magnets enable the easy removal of algae. By dragging the Mag-Float on the outside of the tank, the Mag-Float on the other side of the acrylic surface follows, scraping off the algae with the pad. Most impressively, you will no longer get wet cleaning off the algae from your aquarium because the Mag-Float simply float up allowing easy retrieval. $25.00
