I just don't think your product works as well as Chemiclean. As per past posts, many, incl myself, have had good success with Chemiclean.

In my case, I just turned off the skimmer, and followed the instructions exactly, since I had plenty of flow and aeration in the tank already. I turned it back on after the water change.

One treatment, and cyano was gone for good. Corals and fish were not affected.

Either way. I put a filter sock on and removed all the cyano manually

One other thing I should mention with my mine, is that I started using MB7 (beneficial bacteria) after my Chemiclean treatment. I had already been using it with my other tank with my bio pellets as cyano preventative (and never did have cyano in it). The theory is that beneficial bacteria seeded by MB7 out competes cyano.
