Review on Jasonwell Magnetic Aquarium Fish Tank Glass Algae Cleaner - Floating Brush (L Size) by Deep Echemendia

I'm glad I actually tested all the features on this before I reviewed it, or I wouldn't have been giving it a fair review. The pad surface that cleans the inside of the glass is just okay. It removes grime and algae, but it takes quite a bit of scrubbing. I also wish the magnets were a little stronger, but given how much cheaper this thing is than the Mag-Float, I think it's fine. The best feature though is the plastic scraper attachment. It leaves the glass perfectly clean in one pass, and you can go all the way down to the bottom of the tank without disturbing your gravel or substrate. And the best part is that as long as you wait for a little build-up and scrape the tank from top to bottom, most of the gunk and algae comes off in big globs instead of tiny bits and stays at the bottom of the tank. Wait a bit for the rest to settle, vacuum it out with a siphon, and you're good for another 2-3 weeks!
