Liek coach said, you need the high wattage to reach the bottom of the tank... they done make N.O. lights for a 55 any higher then 40W
with the lights i sent you yesterday, you will have no problem keeping anything.. LPS, SPS, clams, and defiinitly your carpet!
Just go to some sites and show him some pics of corals.... if he is that interested in teh tank, hell jump at it!
