Cleaning algae off the inside of your fish tank is a chore, right? Especially in small tanks where your arm barely fits. This tiny magnetic cleaner makes it a total breeze! It’s made of two parts: a soft-bristled brush that goes inside the tank, and a magnetic handle that stays outside. You just stick them on opposite sides of the glass (for glass thickness between 3mm and 6mm), and the strong magnet holds them together tightly. Then, simply move the outside handle around – the inside brush follows along, scrubbing away green algae, gunk, and water stains without you getting wet. The bristles are soft enough not to scratch the glass. The whole thing is really small (about 3.7cm x 2.5cm), so it’s easy to store in a corner of the tank when not in use and it’s perfect for smaller aquariums or for getting into tight corners in bigger ones. The plastic shell is waterproof and ergonomic. A must-have tool for any aquarium owner to keep the view crystal clear for you and your fish. (Important safety note: Not for use by people with cardiac pacemakers due to the magnet.)
