"A magnetic algae cleaner which is suitable for acrylic aquariums with a thickness of up to 3mm. Simply place the felt sided magnet on the outside of your aquarium and place the opposing magnet inside the aquarium. Join them together with your aquarium wall inbetween and start moving the outside magnet leading to the removal of algae from your tank. You can even leave your magnet attached onto the aquarium sides if desired for easy re-use. We advise to never use the magnet above the water line or on dry surfaces and always remove debris from the magnet before use."
