Just purchased and set up a 72 gallon bow as a reef tank about a month ago. So far I have 85#s of live rock and 4 fish. The fish have been in there for about 2 weeks with no problem. With that said I am a little unclear of exactly what I need to be testing for, I get confliciting stories. I have been told I need to test for Nitrate, pH, Calcium, & Ammonia. Is there anything else I need to test for? Also, I have seen test kits that include Success Supplements such as Strontium, Molybdenum, Iodine, and Trace & Green, do I need all these supplements in the kit? So far I have been using a pH booster along with another additive to boost the Calcium.
