Magnetic Aquarium Cleaner
The Mag-Float Aquarium Glass and Acrylic cleaner allows you to clean the inside of the aquarium walls without getting wet! The rough cleaner side on the inside of the aquarium clings to the smooth side of the magnet on the outside of the aquarium. Perfect for small to large aquariums. Very large aquariums over 130 gallons will require a larger magnet due to the width of the aquarium wall (needs higher magnetic attraction).
