So my skimmer is now making a dark foam but still not enough to fill up the collector. Now i am getting an outbreak of cyano(i'm petty sure that is what it is) growing on the rocks. I tested and still amonia,nitrate,nitrite, phosphate at zero. Something has to be there! i only have 4 anthias and a royal gamma as far as fish go in a 90 gallon tank.Didn't have any trouble before the anthias, maybe i am overfeeding them? You would think the skimmer would be going cazy if that were so. All of my corals are going great so far.
