I have a year old tank and recently got cyano everywhere back wall rocks sand, it’s covering corals long stringy dark red, I used cyano rx it went then came back and is now immune to rx my flow is good and nutrients being no3 at 3 and po4 around 0.09 on icp and 0.05 on Salifert, I tried refresh also to no result, mb7 did dent it slightly but it’s free back in a day, it was caused by nopox and I’ve winded stopped it’s use, do I wait it out or is there some other way I can try get rid of it?
