I'm having cyanobacteria out break, my tank is about 7 months old (60g cube) I had a small issue with cyano a few months ago but thought it was just new tank growing pains and it went away pretty quickly. But the last few days it has come back pretty bad covering the sand pretty quickly. The only change that I have done is add a few new pieces of dry marco rock (maybe 8lbs) I'm not sure if that could be the cause? My nutrient levels are Nitrate: 8-12 (redsea) Phos: .03 (hannah) I run a fuge and reef octopus 110 classic ss in a trigger 26 sump. I also do about 1.25g daily water changes.
