Chemi clean worked like a charm for me. It took 2 tries but I beat the cyno problem. What I did was a 10-15% water change before you use the chemi clean and then dose... then do as the directions indicate. There must be something causing the cyno problem so this will only be a temporary fix until you find and cure for the problem. It had no effects on my fish or corals.
HTH Good luck.
