Effect of Coral Snow on Cyano

[KPG007]

I use Coral Snow religously and it did nothing with my cyano. It does, however, help, as my skimmer goes into high gear, pulling out lots of junk after I add it.
I used chemiclean to get rid of my cyano and was really happy with it. Follow the directions and in about 7 - 10 days it will be gone and your skimmer can go back on line.
