200 gallon reef tank metal halide help!

[Vishaalkumar]

hey guys i have a 200 gallon tank 72"wide and about 36-38" tall i have two 36" coralife lunars HO right now and clearly isn't enough light. I was wondering what kind of color temperature would be best suited as i want to be growing sps and lps as of what kinds of corals i haven't decided but the ones i have looked at seems to have a high demand of light. im going to desing a canopy with probably 3 MH if you guys can tell me what wattage and color temperatures to go with it would really help thanks
