Algae are nunmal a problem with which every aquarium owner must grapple greater or lesser extent. Especially in a densely planted aquarium, the cleaning of the discs and removal of algal growth is quite a challenge, since one does not want the aquatic plants while damage. After several attempts with sponges and other tools for window cleaning I was very frustrated because even with the strongest effort, the algae could never remove 100%. I was already on the verge of giving up and losing the joy of my aquarium. The Tetra MC Scheibenreiniger would be my last attempt. Honestly, I ordered it with no major expectations. The first surprise of the box was the strength of the magnet. In dealing with it should be a bit careful, otherwise you can quickly time to pinch a finger. Use the aquarium ran without any problems. Most places were immediately clean, particularly stubborn problem cases to which it quite particularly mattered to me, needed a little more, but in no time all the windows of the aquarium of algae were exempt. I would recommend this highly enough Scheibenreiniger. The manufacturer specifies a maximum slice thickness of 5 mm. With regard to the strength of the magnet it should also work with thicker slices, in which it should be remembered, of course, that it is the effectiveness of the cleaning could be less.
