Review on Gulfstream Tropical AGU00259 Mag-Float Mini: The Ultimate Glass and Acrylic Aquarium Cleaner by Karla Harper

The magnet is not strong enough. Too weak to scrape algae off my 1 gallon acrylic betta tank. And also the product doesn't look like a real mag float magnet. I have two original Mag-Float magnets of different sizes that I bought at the store. A real mag float will have a patent number on the back of one of the magnets. The magnet I have now bought does not have a patent number on the back. Although the photo in the product description states the patent number. My two mag float magnets are light gray. The magnet I have now bought is yellow-grey. I would not recommend buying this product. After spending a certain amount of money, you may feel disappointed.
