I've been battling this problem for the last month or so and I am getting very frustrated now. I am reading all the threads and the wealth of information is overwhelming. I believe I caused this by dosing NoPox, bringing my nitrates down too low. I added an algae scrubber at the same time. I have since stopped dosing and removed GFO. Nitrates are around 5 now and Phosphates are .05 at last check. I am siphoning the sandbed every other day into a filter sock and I added a UV sterilizer. Nothing seems to work. I do have the algae scrubber still going with my thought being the algae growth would help to out compete the dino's but I'm not sure if that is how it works and maybe I should shut it off for the time being. My next step is a 72hr blackout but before I do that I am hoping to get assurance that I am actually fighting the right plague. My more sensitive corals are now starting to show serious stress and I have even lost a couple. I appreciate all the help from the R2R community.
And what the heck is this???
