Okay I dont have it yet, still in the planning process. Im setting up a 75g FOWLR. I plan on getting the live rock from liveaquaria. I'll be getting (2) 45lb boxes. How should I do it, just buy all 90 lbs and throw it in at the same time? I know I shouldnt cure 45, then add the other 45 uncured right? How should I go about doing this? Oh and there wont be any fish in the tank until all 90 lbs has been cured.
