Sera - Magnetic Glass cleaner - XSM

Algae layers on the aquarium glass not only obstruct the view into the aquarium but can often only be removed by reaching into the water or when changing the water. With a magnet cleaner, however, the glass can also be cleaned quickly and easily from the outside. The Magnet Cleaner Floating is a classic magnet cleaner that is characterized by its floating properties, among other things: If the inner part detaches during cleaning, it floats upwards on its own and can be removed from the aquarium without any problems. This also minimizes the risk of sand or fine gravel being trapped in the cleaning surface of the magnet. The outer magnet is covered with fine velvet and reliably protects the outside of the glass aquarium. Works on glass up to 4 mm (0.16 in) thick.
