My Alk(6.7)and Ca(330)seem to be pretty low with a specific gravity of 1.025. This is a newly established tank (BOD 12/3) i use red sea coral pro. I dont have a mag test kit yet so i cant report any #'s on it. All other parameters look good ph8.3, p04-0. Is this normal? I feel that my Alk and Cal should be higher. I have 0 corals and 4 chromis, 1 firefish goby. I was going to add my first corals like a LPS or softie but I decided not to yet. I plan for a mixed reef with a few easier to keep sps. Oh and i run gfo, skimmer is running and i have lots of Chateo. And thoughts? Or am i good? Thanks in advance
