The only scraper you will ever need. The attached razor gets ANYTHING off your glass.
BEST Scrapper EVER
If you are looking for something that will literally clean you glass and not work about the magnet coming off while cleaning and you having to try to grab it before it float away, this is the cleaner for you. As the other review mentions, this magnet is a string magnet; definitely better than any other cleaner that I have purchased. Absolutely worth the money. Using it on my 210. Used Mag-Float and Tunze (the worst seems like) and this bad boy hands down kills them in performance.
Works great on my 330 gal tank. Unlike my previous scraper, does not separate from the magnate if I try to go fast. The magnet is so strong that it can make my arm a bit tired if there is a lot of algae.
