Review on Compact Marina Algae Magnet Cleaner for Efficient Tank Cleaning by Angela Tarpley

Exactly what it says. It removes algae from the walls of my tank without having to put my hand in it. Sometimes it takes a few passes to remove really thick algae and the cleaning pad might need a few rinses before you're done cleaning, but it works really well and is one of the best purchases I've ever made . my tank. The string ties the two magnets together in case you lose contact with the contents, so you don't even have to reach for it when you're done. Highly recommended.
