New and Revolutionary Cleaning Magnets! These are the strongest floating aquarium algae cleaning magnets available that are safe for glass and acrylic aquariums. The inner cleaning assembly is made of high quality injected molded durable ABS plastic.

Benefits of a "floating" inner cleaning assembly:

• Enables vigorous algae scrubbing without worry of detachment and having to dig the cleaner off the bottom of your aquarium, scaring your fish, damaging the aquatic environment, and ultimately getting all wet.
• Strong, impenetrable injected molded durable ABS plastic inner magnetic housing is fresh and saltwater safe and will not corrode or rust. Therefore, you can leave it in your aquarium all the time.
• When substrate, gravel etc. get caught in the cleaning pad of aquarium algae cleaning magnets (which does occur from time to time) you can just disengage the inner assembly and it will float to the top so you can clean off the scrubbing pad. No more scratches.
• Lighter inner cleaning assembly makes for a stronger magnetic attraction, better cleaning ability and easy maneuverability around corners.
• No more strings to get tangled.

• Aquarium Thickness: glass = 3/4" & 1"; acrylic = 3/4" & 1"
• Aquarium Size: 300-600 gal
