Also helps to have strong lighting. I have a 14K phoenix 150W metal halide right over top of it with 2 actinic t5's on a small tank.

In the edge, I don't think I will need to keep the calcium that high. I will aim for around 380-400 ppm for this tank as it will have some LPS, a small clam,and some easy SPS.
