I haven't any SPS corals in my tank and that is a problem (upside) that I am wanting to correct (downside) I really haven't a clue other than you want low Nitrates and a calicum level around 400. Is there a book out there or a web site, something to get me going in the right direction, I would hate to buy corals just to watch them die. I have read post by some where there nitrates were low calicum just right but they were having PH swings and their sps corals were'nt doing so good. I know this can happen to anyone in this hobby but I would at least like to have a good understanding of where I need to be in the tank from the start. Thanks for your time.
