When changing from fwlr to reef, I would like to replace my substrate, like 1/3 at a time. I'll replace it with fresh argonite sand as I go along. I feel it would be best if I did this before thinking about buying any corals. Also, would it be better if I bought rock, not live rock, set it up and let it get live in time. Please give me your thoughts. Thanks.
