Aquarium: This device cleans glass by magnetizing from the outer pad to the inner glass cleaner section for quick and easy removal of algae growth, keeping your aquarium healthy and looking its best. PREMIUM QUALITY: The Brush surface is made of cloth with small hooks to scrape off algae without damaging the glass. The handle surface is covered with felt on the outside so it slides easily when cleaning. COMFORTABLE AND NON-SLIP: Its long and wide pole shape makes it easy to reach, a large thick handle makes it easy to hold when you move, and the non-slip handle is also very convenient. Floating and easy to store: It floats, so you don’t have to worry about it sinking to the bottom of the sink, and you can get it out without your Wetting hands or disturbing aquatic animals or plants."
