Just acquired the 72" Aquaticlife T5 HO (4 x 39 watt whites and 4 x 39 watt actinics) light fixture w/ LED moonlights. I have the smallest colony of Xenia (smaller than dime sized) on one rock. Planning to obtain some yellow polyps soon. I plan to upgrade the bulbs w/ ATI bulbs at some point. But as it stands now what are my limitations in terms of what I can keep and what I can't? Tank is 125 gallon, 72" x 18" x 24". Thanks!
