CS is not a cure all when it comes to cyano or diatoms, but it does seem to help (for me anyway) some of the other benifits are as stated, water clrity and also it acts as a biding agent for foods that will either be skimmed out or assimilated (KZs words),,,,,I try to steer people away from "chemical" solutions before trying to figure out whats causing it

I'd have to agree. I tried the coral snow with no effect, tried the 3 day black out that worked for a couple of weeks, but it still came back. I cut back on feeding, changed bulbs , dosed vinegar and added more flow, but the cyano wouldn't go away. I'm now convinced that it has to be my DSB as I hard a larger bioload before and had no problems, but I now have convict blenny's that stir my sand bed around a lot. Rather than looking to a chemical solution, I'd go through the steps fishytime has stated, or it is just going to keep coming back.
