Read about fishless cycling: http://www.aquariumadvice.com/showqu...q=2&fldAuto=15
You add a piece of raw shrimp to the tank, it decays, creates ammonia, causes the tank to cycle properly, and then you can safely add fish.
No one here is going to advocate cycling a marine tank with live fish. Its 100% un-necessary, because a fishless cycle will make the tank healthy without ever endangering the lives of any fish.
Live rock can help speed up the cycling process if it's already cured. You'll pay more for cured LR
than uncured (from member's posts, I'd say cured LR
is 50-75% more per pound than uncured, which around here is all I can get, and its $5/lb. you are lucky to live near the coast...LR
is gonna be cheaper and abundant at your LFS
