Actinic Lighting colors?

[fishtk75]

I got a new current nova T5 lighting for my 75 gal. Now I have on my 120 tank 2-250watt with 2 -110 t12 48" VHO UVL actinics. I see the T5 Actinics are blue in color and the T12 are purple in color. Question is blue or purple color better for coral? Asking as see more colors to pick now.

Also the T12 runs by a Ice Cap 430 ballast. Will the 430 ballast run two T5 HO 54 watt lambs? Looking at changing caps and putting T5 lamps.

Are the VHO bulbs the "super actinic"? That is what I run on my 300 in both the 3' and 4' lengths.
I do think that ballast will probably run the T5, but you are going to want to make sure before changing.
