Marina Algae Magnets for glass aquariums allow the cleaning of inside glass walls without getting your hands wet! The Algae Magnet works similarly to the Mag Float, using a powerful magnet on the outside to guide the cleaning magnet inside.

• Easy removal of algae from aquarium glass
• Heavy duty permanent bond pad
• Will not scratch aquarium glass
• Small Algae Magnet Dimensions: 5.8"L x 3.9"W x 1.8"H
• Large Algae Magnet Dimensions: 6.5"L x 4.8"W x 1.8"H

Both magnets exert powerful attraction to ensure a tight, secure grip. The inner magnet features a non-abrasive cleaning pad that will not scratch or damage the glass. Safe for fresh or saltwater aquariums.

Note: Use on glass aquariums only.
