Review on Efficient Magnetic Aquarium Glass Cleaner & Brush: Saim Fish Tank Cleaning Tool by Tracey White

Positively surprised! I was expecting this magnet to be subpar or cheaply made for the price, but no, it's solid, well made and does the job perfectly! The price saved me $$$$ and I'm so glad I bought this scraper. Removes algae and coral from glass with ease, maneuvers between tight spaces where coral and rocks are near the glass, and the magnet is very strong, also note that it FLOWS! I have a 90 liter aquarium.
