The Vevor aquarium gravel cleaner is designed to simplify water changes and substrate cleaning in medium to large aquariums. It uses water pressure for semi-automatic operation, so no electricity or repeated manual pumping is needed. The 25' PVC hose helps reach distant faucets, while the long gravel tube makes it easier to clean deeper tanks without putting your hands in the water. Brass faucet adapters in multiple sizes improve compatibility with common bathroom, garden, and kitchen faucets. Its built-in filter net helps keep sand out while removing fish waste and debris efficiently.
