i keep mine under 110w VHO's and 400watt 20k's. so far so good ;p
I'm planning to set-up a relativly small tank, 20g w/20g sump, reg flourscent lamp with a large focus on natural/biological filtration and feed very heavily with a variety of food. I wanna keep all non photosynthetic gorg's and sponges. I might even have an auto doser for some of the food, like a kalk drip.
