The inner magnet is more than 3 mm (.2") 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. With Care BoosterThe Care Booster literally gives the 2020 Care Magnet upgrade a new “boost”.Two floats with 4 retaining clips, which are supplied with Care Magnet long, strong and strong+, ensure that the Care Magnet’s inner cleaning magnet can float to the surface as soon as it detaches from the outer magnet.The Care Booster can also be used as a convenient grip aid for the outer magnet. Features:• The patented principle, which uses plastic blades with a different length, creates a varying application pressure, enabling the narrow blade to remove even tightly attached algae. With the wide blade, it is possible to perform a large-scale algae removal.• Thanks to its slim design, the plants and the corals will not be disturbed.• The Care Magnet can also be used on round aquarium panes or round-arched panes.• Plastic blades with round edges enable a smooth transition to the next pane at the aquarium edges without damaging the silicone joints.• It doesn't distribute the algae within the aquarium as a green dust; it rather roles them up completely, and through this turns the algae film into actual food for the fish.• With coloured end caps.• It can also be used as a hand scraper. Care Magnet Long Specification:Suitable for glass thickness: 10 - 15 mm (3/8" - 2/3").Width: 86 mm (3.4")Length: 140 mm (5.5") Includes:1 stainless steel blade,2 spare plastic blades,2 Care Booster,4 clips,8 coloured end caps (blue, green, white, black).
