Bulb/Actinic combo

[flyguy]

I'm just finishing a custom hood for my 55gal. I've got a dual 175mh setup and curious about what bulb to get and what else to add. What about actinic or daylight PC or VHO additions? This will be my first real lighting system. Currently have no coral, just 65lbs LR. looking for suggestions to host variety of corals & clams.
