I used it in my 100 gallon black Rubbermaid tank (which is on the north side of the barn) for two months this summer. This helped remove the "slime" but I still had to clean it up. I just didn't have to grind as much. After about 6 weeks it didn't seem to be that strong anymore. I could use it again.
