Floats to the surface, no need to “fish around” in the aquarium any more if the inner part detaches from the magnet on the outside of the glass.

• No more scratched glass as inner section never falls into gravel, picking up small stones which can scratch glass!

• Angled edges protect silicon seams of aquarium.

• Protruding edge makes cleaning behind technical equipment easier.

• Shaped grip of outside magnet for easier handling.

For glass strength: 15 mm
