Algae Free Magnet Cleaners

The "Hammerhead Float", "Tiger Shark Float", and "Piranha Float" are a revolutionary development in aquarium algae cleaning magnets. The inner cleaning assembly is made of high quality injected molded durable ABS plastic, which, when disengaged from the outer assembly, floats to the top of your aquarium. These magnets are a smart investment, and they'll virtually last forever.
