First off this is my first post. I am new to marine but not to aquariums. I have had freshwater for a few years and am planing to move to salt very shortly. I will be setting up a 46 gal FOWLR and i am just trying to iron out the details. I know i should strive for 1.5 - 2 lbs of live rock for the tank, but to start i would like to use both base and live rock to lower the initial setup cost. What mix should i aim for, and how long will it take to mature? Thanks
