Light Combination Question

I have just finished my 110 Gal build and for lighting I chose 2 - 250 Watt 20,000K Metal Halide Pendants. I also have a double 58W HO T5 ballast with an actinic bulb and a 6500K bulb. My plan is to have the HO T5's come on before and after the MH's for the sunrise/sunset effect. I do have a couple of concerns;

1. Are the T5's redundant with the MH lights?
2. I thought the 6500K would benefit the growth of the corals, but would the more powerful MH lights cancel out the 6500K somehow?
3. With 20,000K MH do I even need actinic?

I don't want to be paying electric bills for lighting I don't need, but at the same time I want what is best for my corals. My HO T5 is a Hagen GLO fixture and my only options are 6500K, 18000K, and actinic.

 

Anyone???

 

Hopefully better late than never. The T5s are not redundant, but I would only run actinic bulbs in them. You do have 20,000K MH so you could probably get away without using the T5s, my T5 actinics are 22,000K in comparison.
