Well im a convert after being cloaked in failure for the last 8 months in my 30 gallon dsb sps tank. Im moving on to bigger and better thing Im moving up to a 72 reef ready bow front. So far i have it set up for a closed loop set up connected to a 4 way squirt. 2 250 watt mh and 2 110 vho's in the canopy. And a vs3-36 for a skimmer which is rated for about 5 and half times what my tank size is. Im not sure how big my sump should be and what kind of pumps I should be running. Also how much rock should i have in my tank ive been going crazy because im was on Reef Central and theres no one really there to anwser my BB ques.
