Coral Snow is a great product...but I haven't had success with it as a cyano treatment.

When we first took over the store from it's previous owner, the display tank was in sad shape. Nearly every inch of the sandbed was covered in cyano. It was an old deep sandbed that had never seen adequate flow and was loaded with organic waste. I dosed it about 8 times with Chemi-Clean (which is normally a very effective product). It would put a small dent in it for a day, and then it would be back as strong as ever. What finally put the cyano down was treatments with ZEOzyme and ZEObak.

Chemi-clean I use first to get rid of the immediate symptoms. ZEOzyme and ZEObak help get rid of the excess organics problem. Of course, flow, protein skimming, feeding, nurient levels, also need to be examined.
