Hello everyone. My NDOC results have shown a high level of organic carbon which has caused STN problems in my acros. I stopped adding ReefRoids and Aminos and the problem was resolved. Currently I do not dose anything. I wanted to know if PNS PROBIO AND WELLO PNS can cause problems with organic carbon. @Kenneth Wingerter Could you help me with this? Yesterday I received my bottles of PNS and YELLO PNS
