The Magnetic Algae Scrubber is easy to use. Simply move the non scratch felt lined handle over the outside of the tank and the Scrubber will follow you inside the tank. The piece inside the aquarium floats, so if it becomes separated from the outside magnet it is easy to retrieve. It will even go round the corners of the aquarium! To see it in action watch the video below.
Things to note...
This product is NOT designed for acrylic tanks. Glass only.
When using this product be careful not to get substrate trapped between the magnet and the glass otherwise it will scratch your tank.
