The Easy Blade will make cleaning your aquarium easier! The new Easy Blade gives you the combined cleaning power of a floating algae magnet and a blade cleaner. Quickly and easily remove algae, including coralline algae, in those hard to reach corners. The Easy Blades mounts permanently to the algae magnet with super glue. Easy Blade has a working position and an idle position, allowing you to use just the algae magnet putting the Easy Blade into action for the tougher cleaning jobs. Manual cleaning of the aquarium walls by reaching into the aquarium and using a conventional blade cleaner will be a thing of the past for you. No more stepping on a chair in order to be able to get your arm into the aquarium and no more stepping down from it and up again in order to see whether all areas of the aquarium are clean! Just use Easy Blade standing in front of your aquarium with everything in sight. The blade is fastened safely as to minimize the risk of injury to humans and animals. Caution should be used around silicone joints. The Easy Blade comes with one blade. Replacement blades are available separately. The Easy Blade Black will work with the following algae magnets: * Mag-Float 350 * Magnavore 8 * Magnavore 10 * Piranha Float * Hammerhead Float * Tiger Shark Float * Great White Note: Blades are not designed to be left underwater for extended periods of time. They should be removed from the aquarium after each use.
