You can mix the rock up if you want. Since you have the time, get some dry base rock from your fish store (it's a lot cheaper) and mix it with live rock. Eventually the bacteria will spread to the base rock and become live rock. If your tank is 40 gallons, I would at least shoot for 40-60 lbs if not more just for bioload. A lot of people will go with 1-1.5 lbs of rock for FOWLR
