Mag-Float Cleaning Magnet (Large) Powerful Floating Glass Cleaning for Large Aquariums The Mag-Float Cleaning Magnet (Large) provides the magnetic strength and cleaning coverage required for large glass aquariums. Designed for systems up to 350 gallons with glass panels up to 5/8 inch thick, it allows routine algae to be removed from outside the aquarium while the internal cleaning section follows across the submerged glass. If magnetic contact is lost, the internal cleaner floats for convenient retrieval rather than sinking into the aquarium. The Large model also includes a scraper attachment and blade to help tackle more persistent algae and deposits that may not be removed by the standard cleaning pad alone.

Confirm the aquarium's glass thickness before use and select a different Mag-Float model if the panel exceeds 5/8 inch. The powerful magnets can snap together forcefully. Keep fingers clear and maintain control whenever the two sections are brought together or removed from the aquarium. Store the sections with a suitable spacer between them when they are not attached to the tank. Always inspect the cleaning pad and scraper before use. Remove sand, gravel and other hard particles that could scratch the aquarium. Exercise additional care near silicone seams and aquarium edges when using the scraper attachment. Mag-Float Large Directions Place the internal cleaning magnet inside the aquarium and align the external handle magnet on the opposite side of the glass. Bring the sections together slowly and maintain a secure grip to prevent sudden magnetic impact. Clean the aquarium using slow overlapping passes while keeping the internal section away from the substrate. Use the standard cleaning surface for routine algae and position the included scraper as directed when additional scraping action is required. If the magnets separate, allow the internal section to float upward before retrieving it. After cleaning, inspect and rinse the pad and scraper to remove algae, mineral particles and other debris.
