Title: Good for light algae
Review: I used this on my 80gallon acrylic aquarium and it some-what worked. A couple things to be aware of is that you should make sure there are no tiny snails or other hard items stuck to the wall of the aquarium for fear of scratching. It won't remove algae that is hard to remove in the first place...you may need to get some acrylic safe scrubbing pads and just use some strength to get that off (that is what I had to do).But for light algae removal, this seems to work well.
