Here is my plan. I am starting a 150 gal. FOWLR first and once I have that mastered that, I would like to add some coral. When I have everything, I was thinking of getting 120 lbs of base rock from Hirocks and 40 lbs. of live rock from liverocks. Will this be enough live to start cycling my tank? Can I add more live rock after cycling? I will be adding 2" of sand(50% live,50%dry).
