Mag-Float Floating Magnet Glass Aquarium Cleaner Small

This large mag-float acrylic cleaner is built for serious tanks—up to 350 gallons. The magnet is strong, so it holds steady while you scrub, even on thick glass. If the pieces separate, the inside part floats up so you’re not reaching in. It scrapes off algae without scratching the surface, and covers a lot of area in one pass. If you need a heavy-duty aquarium algae cleaner that makes tank cleaning way less of a hassle, this one’s solid.
