Mag-Float Scrape floating magnet cleaner for easy cleaning of aquarium glasses. The algae magnet cleaner sinks not to the ground but is floating upward, to the water surface, if the connection to the outer part is lost. The Mag-Float Scrape comes with a sharp blade, which is removable.https://www.aquaristikshop.com/aquaristic/Mag-Float-Scrape-Magnete-cleaner-with-blade-floating/278106/
