I have used tham all. Ive used PC's T5's VHO and MH.
I currently run the following:
72"L 30"H 24"W 230 gallon.
3 X 400 SE metal Halide 10K XM's (PFO tar ballast)
2 x 6' VHO Actinic
Actinics on for 12 hours, Halides on for 8 hours.
I keep SPS, zoo's and other LPS corals. I find the Metal halide bulbs wash out some of the zoo's color, where as PC's made my zoo's look the best.
Everything seems to grow well under this lighting combo but I may add another 2 VHO for a more blue look. I like the metal halides the best out of all the lighting combo's I have tried.
