This glass pane cleaner avoids scratches on internal aquarium glass panes, and can therefor even be used on acrylic glass panes with the small plastic blade.
The inner magnet is more than 3 mm (.2 in.) away from the aquarium and thus prevents the jamming of the aquarium sand. The two plastic blades remove the algae considerably better from the glass panes than a flat cleaning surface – almost as good as a sharp metal blade. The life of a blade is from several months up to approx. one year. The low flow resistance during the cleaning with a simultaneous high magnetic coupling, makes a separation of the magnet nearly impossible.
The large blade should only be modified with the included stainless steel blade for aquarium glass panes with particularly tough algae, e.g. older deposits on the side walls or thick calcareous algae.
For panes with a glass thickness from 10 mm (3/8″) to max. 15 mm (1/2″).
Width 86 mm (3.4 in.), length 140 mm (5.5 in.).
Including a stainless steel blade and two spare plastic blades.
