I totally agree with the advice
Gourami Swami
is giving I also have experienced what he has said about a reef setup. Before some of you were born it was far more difficult to keep a reef going do to lack of information there was no Google or YouTube to go to. The only resource was magazine's and book's. I've lost expensive fish and invertebrates during that time. My lighting was metal halide which made the room a seem like the sun was in it lol. Nobody wants you to fail that's all it comes down to it. Please research reef forums and youtube like suggested.
