Going back to halides. Bulb questions

I run a 4 balb t5 Icecap on my 75. I just scored 2 250 watt halides. I am planning on keeping the 4 bulb t5 and just adding the halides. They have two month old 10k. Was going to run the 10k and do three blue plus and one purple plus. Too much??
 
Sounds good for about anything, overkill for mushrooms but everything else should love it. Start slow, a few hours a day and then increase the time per day. You may also want to place the MH higher over the tank when you start and lower them over a few weeks. Another option is place your corals lower in the tank and then move them up over time. Just a thought.
 
I'd run 2 true actinics (420nm's), 1 purple plus and 1 blue plus. You'll get all the par you need from your mh's so you don't need to worry about not getting any from the 420's. On 2nd thought, since you're running 10k halides I'd probably ditch the purple plus and go with 2x 420's and 2x 454's. Once the 10k's are spent, I'd replace them with 20k's and then swap out an actinic or blue+ for the purple+ .
