Tunze Care Magnet Long

The Tunze Care Magnet Long is a high‑quality magnetic aquarium glass cleaner designed for tanks with glass panes between 10 mm and 15 mm thick. Its inner magnet sits more than 3 mm from the glass, so sand or grit is unlikely to get trapped and scratch the surface. It uses special wear‑resistant plastic blades that clean algae more effectively than a flat pad, and for stubborn buildup you can swap in the supplied stainless‑steel blade. The design ensures strong magnetic coupling and low drag, making algae removal smooth and safe — even on curved panes — while minimizing disturbance to corals, plants, or décor.
