I had terrible brown algae. A tank cleaning worked for a week and it was back. I tried this product and after a second application my tank has been crystal clear. Fish seem to be fine.

I am disappointed at this product. I have used several Tetra products....this one DOES NOT do as advertised.
Unable to use

I was looking forward to trying this in my tank to help control some of the excess algae, but was unable to use it as I have crustaceans and invertebrates in my tank. I wish the information on the website would have listed this as an issue.

Did not work for me

I saw no improvement with this. Arizona water is not the greatest and I have some major algae growth at times and this made no difference in treated tanks even after repeating treatments and large water changes. My water comes from a holding tank and may be too complex for this to handle.

Great - really works - my fish are much happier - tank stays clean longer!

I used this on a planted aquarium that had an algae problem. Works quite well if used as directed. As a side note, one of the plants I have in that aquarium is a Marimo "Moss" Ball (it's actually a type of algae), it was not negatively effected at all, so this product appears to be safe to use on them as well.
