Ok, I think it has been long enough to post my results. Nothing extremely insightful except that my new lighting setup has helped with my colors tremendously. I had always had a problem with purples and blues and the new lighting has really improved those colors.

From the few tanks that I've looked at and tested with a light meter I've found that around 350-500 PPFD seems like the right amount of light to be hitting sps corals. Now this can be achieved with a wide variety of lighting setups and I am not say that everyone s/b going with 400W MH's.

My recommendation is this (which has already been stated in this thread): Find a commonly used setup for your size tank that has proved to be successful and go with that.

	MH Metal Halide Lighting, typically used for high intensity light demanding corals such as SPS. Bulbs come in varieties of spectrums (7k, 10k,20k), and intensity (175W, 250W, 400W).

	SPS Small Polyped Scleractinians - Sometimes known as Small Polyped Stony corals. These are hard corals that have extremely small polyps. They are typically on the difficult side and require Metal Halide lighting or dense Power Compact or T5 arrays. These corals are prized for their rareness and ability to be easily fragged into multiple colonies.
