i have used these for years. Will keep your glass clean. the magnet is strong and the scruber works well. I have a 80 gallon tank and use the medium size

This cleaner was easy to use and made my glass on the aquarium's look cleaner than it has been since i've gotten it

I use this on my 75 gallon freshwater tank. It's easy to keep the glass clean and it even helps with the exterior. Doesn't scratch the glass, just careful with sandy bottom

This is so easy to clean the aquarium glass

Amazing aquarium glass cleaner keeps my aquarium glass sparkling clean

This is the best cleaner.

Works great for my 55 gallon fish aquarium

Very powerful magnet, be careful placing it on the glass. With that said it's a pleasure to use because it wont fall off like other brands. It's a rough type of texture and I actually put a filter pad on it to make it easier to glide along the inside of the glass which also makes it very effective to clean the algae off on the first swipe. I love this solution and I guess it's as good as it can get for a long lasting cleaner.
