Mag-Float Glass Magnetic Aquarium Cleaner with Scraper, Large

This is a revolutionary magnetic aquarium cleaner, unique because it floats. Its buoyancy makes it easy to operate and easily guided around corners without sinking. The cleaning brush stays free of sand or gravel, preventing scratching, and the strong attracting magnets easily remove algae. Made with high quality cleaning material and felt, high grade ABS casing. Glass only. PLEASE NOTE Make sure you keep the separator between the magnets. It is very difficult to separate the magnets if they connect without the separator in between! Watch your fingers, too!!!
