Magic
This product is like magic... in 48 hours your cyano will be gone. But you have to use it with caution ... pull out your skimmer cup during the treatment and let the skimmer overflow for oxigenation. In my case i've made the WC after 36 hours because i saw a same of my acros had their polyps retracted . After WC and after i added carbon all was Ok and i'm Cyano free.
