New packaging: Dimensions: 10.5 x 5.5 x 7.3 cm. Suitable for aquariums with a diameter of 80 to 150 cm and a thickness of less than 12 mm. Also suitable for aquariums with a diameter of approximately 50 cm and a thickness of over 8 mm. Floating design: Thanks to its powerful magnetic attraction, the inner magnet follows the movement of the outer magnet, thus cleaning the glass. The floating system prevents the brush from sinking to the bottom of the aquarium and makes it easy to remove. Multifunctional: The ergonomic, non-slip handle ensures a comfortable grip and optimal cleaning. The scratch-free pads are very effective in removing algae from the glass, saving time and effort. Special design: Our magnetic aquarium brush consists of a cleaning surface, an inner magnet, an outer magnet, and a non-slip handle. This streamlined design is both aesthetically pleasing and stylish. Suitable for all types of aquariums, large and small. Square or rectangular, our magnetic brush is the perfect choice. However, do not use it on an acrylic aquarium.
