Mag-Float Floating Magnet Acrylic/Glass Aquarium Cleaner Mini

This mini mag-float acrylic cleaner is a solid pick for smaller tanks—up to 10 gallons. It floats like the bigger ones, so if it slips off, you’re not reaching into the water. Works on both glass and acrylic, and the cleaning pad is gentle enough that it won’t scratch anything. Strong enough to grab algae, small enough to move around tight spaces. If you’ve got a nano tank or something small, this aquarium algae cleaner makes the job way less annoying.
