Works great!

This thing works so good! After each use, I take it out of aquarium, clean it and let it dry, so it doesn't fall apart. I highly recommend this product!

Magnetic aquarium glass cleaner

This is a strong magnetic aquarium glass cleaner that is perfect. It’s great because I don’t have to put my hands in the water and I can clean the tank more often.

It's safe and won't scratch glass

Had these for around 20 years and it beats a razor blade for getting algae off the sides of the tank. I've cut the silicone on the sides of the tank with razors and caused leaks and scratched the glass. This won't do that. I don't even take it out of the tank. I just push it in a corner when I'm done. It reminds me to take it across the glass in passing. When the inside scrubby pad wares out you can take it off and replace it with a green scrubby you use for dishes. Just don't use the one you've used for dishes. That might kill your fish. Use a new one and cut to size. They last long but after some years it will need to be replaced. The magnets will start losing power to connect. Buy one. You won't be sorry.

Unfortunately, not your grandmother's MAG-FLOAT!!

I always thought this was one of the best items to come along for aquariums. I had my last one for YEARS!!!! Well, my dog grabbed it off the aqua glass one day and chewed it up!! Time for a new one. I got this medium MAG-FLOAT in February of 2021 and as I was using it a few months ago, I noticed glue streaks on my glass!! I took it off and saw that the felt was coming off!! This is so wrong. Not even a year. I'm going to ask for a refund. Other than this, I love and use auto-ship every month.

I wouldn't buy this again.

There was a tiny burr on the padded side of the float that put 2 - 4" scratches on the front of my aquarium. Beware!!

Great product!

Since I changed several years ago to all live plants, I was cleaning the glass with a razor blade scraper and scotch blue pad. It worked, but was messy. I ordered this tool, and was overjoyed the first time I used it! It takes a couple minutes to do the whole aquarium, and I don't even have to open the cover. 5 stars- highly recommend! I got the Medium, which is good-sized.
