Thanks Scott, for that bit of info. It was just what I needed to fine tune my tank. The 20:10:1 stuff. One more question. Is there something I can purchase at a nursury that will increase my PO4 and not effect other nutrients? I have been using a PH up that is hard to find in Corpus Christi area. Most PH controling solutions are PO4 free. ck --------------------------------- ALL-NEW Yahoo!
