It seems all of everyones advice has paid off for me. Everyone has stressed to me research..and that I have been doing. What I have found is I am doing things backwards. I was thinking of transforming my 12year old 90gal. into a reef tank but I also have a 120L that should be the canidate for it. question..1 how should I store my LR properly?Q2 Do I have to have a pre-drilled tank to have a sump or fuge?Q3 Will be about lighting but that can come later.Q4 can I start some things now in like a 30gal. to be used later,if so what? I am going to tear down the 120 completly and do a build thread on it.
