airmax ecosystems cc021-8 CrystalClear, 8 -ounce, OneFix Pond Cleaner

This one really works!!! I tried other brands with no success.then the girl in the local pond store recommended CrystalClear in the middle of last summer. The pond water cleared up in a few days and stayed clear the rest of the season. I added the indicted amount every other week, alternating it with my MicrobeLift bacteria. I am very pleased with CrystalClear and would very lighly recommend it!!!

works fine

Works fairly well, doesn't completely clear.
