Aqueon Aquarium Algae Cleaning Magnets Glass/Acrylic, Small, Black

We really like the Aqueon Algae Cleaning Magnet. It makes keeping the tank clean so much easier and way less messy. It glides smoothly along the glass and does a great job removing algae without any scratching. Plus, the fact that it floats if it disconnects is a great bonus.We probably should’ve gone with one size larger for our tank, just to cover more surface area at once. This one still works great, it just takes a few extra swipes to get the job done. Still, it’s a solid tool and we’re happy with the purchase. Definitely recommend for any aquarium owner!

This really works! It has a strong magnet with two types of cleaning material. It effectively cleaned my tank and had no problem cleaning all 4 sides of my tank without having to lift it off the glass. That's how strong the magnets are.It's very well made, it has some weight to it. The size is good for my 16 gallon tank. Very easy to use I finished cleaning my tank in just a few minutes!

Works well on glass aquarium

Buy the floating model , not this one .

Works SO well. Make sure to go slow, moving to fast will cause the magnetic connection to break.

Best thing I've bought for my fish tank

Bought this to use on my very large aquarium. Intentionally bought a smaller size to be able to fit in spaces without disturbing decor. The magnet on this is incredibly strong and much better than other brands I’ve tried. No issues with it falling off or becoming unattached. Multiple brush textures for acrylic and glass.

Doesn't work as expected. Takes a lot of work to get the glass clear. Also, the dimensions are are not correct in the description
