Bigg D- 3 of those on a 72" tank is going to be just about perfect I think. I put these fixtures over my mixed reef a few months ago and most everything loves it but I did toast a birdsnest, digitata and a kinda boring tabling acro. All the other acros, clams, euphyllias, mushrooms, etc etc are doing just as well as they did under metal halides.
