DIY Retrofit for 120gal Suggestions?

[xxnonamexx]

I have been looking into Retrofit kits for a soon to come 120gal. reef which will host a variety of corals LPS, SPS, zoas, mushrooms, it will be 48"x24"x25" tall I am looking to get MH for this setup I have look into Hellolights and am just unsure the best possible route to go. To me it looks cheaper getting a setup already done. Questions?
Would I need 2 250W MH 20,000K bulbs?
Would I need VHOs?
I know I need a dual ballast and would like the ones that can be controlled individually and sit on the bottom of my stand.
I thought 20,000K makes up for the actinics.
I also read that the double ended bulbs are better. Any suggestions appreciated.

20k bulbs should not require the use of actinic supplementation. However, you may want your reef to be "bluer" than the 20k bulb alone can provide.

little info most reefers stick with a theme lps, sps, softies etc
i mix lps with sps(monti's) good flow and turn over is key
as for your lighting mine before it was 50% 10k and 50% act 03, i now using 14k HQI(only), the color is a perfect balance

In my 55 I have a MH unit 20,000K bulbs only. I have softies and tried soft hard corals I love the hard corals haven't had great success I will probably start with the softies, eventually go with the hard corals. Do you have photos? What size tank?

After doing some reasearch I plan on getting a starfire glass 120Gal. 1 overflow on the back center wall that pushes 1500gph, Eurobraced. In saving some $$$ I plan on building the stand and canopy from getting some great ideas from this various sources. The lighting I plan on sticking with 20K MH 250W and not add VHO's. I have a 55gal with 2 150W 20K bulbs that I like. I also want to keep the electrical bill down lol.
