It probably isn't nitrates. I never had nitrates above 1-3ppm, usually zero. It must be some other dissolved organics. There are some zoas that do better in low nutrient systems though. My mushrooms always reproduced quickly with my low skimming, monthly water change, DSB
refugium based systems. It doesn't work for everything though, unfortunately.
