Review on Jasonwell Magnetic Aquarium Fish Tank Glass Algae Cleaner - Floating Brush (L Size) by Tommy Abreu

I bought this for a tall hexagon shaped tank and it works well. I was worried that it wouldn’t be able to go around the edges/corners, but I was happily surprised that I can navigate the cleaner around all sides. It’s a strong magnetic and must have to keep the aquarium clean! This one is for glass, so make sure your aquarium is glass before buying. They make different ones for acrylic tanks.
