I have been working on getting rid of red slime cyano for several months now. I have been vacuuming it up weekly during water changes, increased my phos removal method and started up my sulfur reactor for nitrates. Nothing has seemed to help so far. Everyone including reef guru Lazy recommends chemiclean. So here goes. I Will post up my results for the next several days good or bad. Added chemiclean today. Pictures are of how bad the cyano has gotten.
