What bulbs are you using?

I am running 3 actinic vho bulbs and 2 400watt 20K Coralvue bulbs on my tank right now. The ballast that I have on the MH is a blueline and a coralvue. When I change them next time I think that I will go with a 14k XM bulb. I like the look of a 20k bulb but would like to get a little more growth out of my corals.
