Review on Ceavmlsr Mini Aquarium Magnetic Brush: Efficient & Scratch-Free Algae Scrapers for Spotless Fish Tanks by Nancy Marie

Nice and compact so doesn't take up much space on the aquarium wall. I bought this hoping the cleaning side would be soft enough to use in my acrylic tank, but it's pretty rough (plastic bristles) and I know how acrylic scratches easily, so I put it in my glass tank instead and used it is ideal for glass. The magnet is very strong so you can easily attach it through the glass. This is a very useful tool to keep the aquarium walls clean when your snail is not doing its job well!
