Key benefits Cleans aquarium glass without putting your hand in the water. Move the outside magnet and the inside magnet brush follows, removing algae and debris from the glass. The inside brush floats and will not sink in the tank, so you won’t lose the cleaning element or have to fish it out. Strong magnetic force holds the inside and outside pieces together through the glass for reliable, consistent cleaning. How it works Two-part magnetic system: an outside magnet and an inside magnet brush. Push or drag the outside magnet along the exterior glass and the inside brush mirrors the movement on the interior surface to scrub away buildup. Floating inside brush design prevents loss of the cleaning unit and makes retrieval easy during and after cleaning. Key features Function: Magnetic glass cleaner that scrubs the inside surface while you control the outside piece. Compatibility: Designed for use on aquarium glass walls. Performance: Strong magnetic force for stable, effective cleaning action. Practical design: Floating interior brush stays accessible and prevents sinking inside the tank. Typical use scenarios Routine aquarium maintenance: Quickly remove algae from the glass during weekly cleaning without disturbing fish. Spot cleaning between water changes: Target small patches of buildup in hard-to-reach corners without draining the tank. Safe, hands-off scrubbing: Clean the inside surface while keeping your hands dry and minimizing stress to fish. Simple usage tips Move the outside magnet slowly and evenly to let the inside brush follow and scrub effectively. For stubborn spots, apply slightly more pressure while keeping control of the outside magnet. Keep the magnets aligned to avoid sudden separation through the glass. Materials and care Designed for repeated aquarium use; rinse and dry after use to maintain performance. Inspect magnets and brush surfaces periodically for wear and replace if bristles wear down or magnets lose hold. What makes it stand out Internal floating brush so it will not sink. Strong magnetic force for dependable coupling through the glass. Straightforward two-part design that makes glass cleaning faster, safer, and less disruptive to tank inhabitants.
