i plan on setting up a 48 inch 40 gal sw tank. my set up is going to be a custom sea life power compact fluoresent with two 65 wat half day light half antic lighting. a prizam protien skimmer and a costom sea life wet dry with a rio 2500 pump. my questions are how soon after i set the tank up can i add my live rock? is it enough lighting and filtration? is ordering live rock off the web ok if its from a reputable place? do i even need a wet dry filter? if not could i still use it in my system? i lost my reciept and cant take it back.
