OK my tank is a 90 gal over a year old with a 20 gal sump and a 5 gal fuge. My bio-load is not heavy, I run a urchin pro skimmer and have 6 maxi 1200 and a mag 9.5 sump return for flow along with my emporor 400 that i took the wheels out of and use for carbon and mech Filt. I started having a cyano problem about 4 months ago and here is what I have tried. Large water changes with RO water, new bulbs, I now only feed every other day, more PH's, switched from Oceanic to Ocean Pure salt, chemi-cleaned two doses with 30% water changes along with vacuming my sand more times that I can count.I also swittched my sand bed out about 3 months ago from play sand to aragonite. I am at my wits end and need some help. I love my tank but HATE this cyano. My nitrates are at zero so I'm not sure what to do. HELPPPPP!!!!!
