Thanks for the info, I'll check out reefgeek. 
I would only have to purchase three new bulbs, as the fixture already has two blue+'s and one of the good Giesemann actinics (not sure which one). I think I've spent half of my work bonus already, and I haven't even gotten it yet, lol.

If you have to get 3 more bulbs/switch out 3 bulbs, I would get 1 KZ Fiji Purple and 2 ATI Aquablue's to add to what you already have.
Pure actinics don't have very high PAR, the ones I suggested will be better in that area.
Here's a link to GrimReefer's study:

Click on Lamps on the left, then click on PAR readings and Combinations.
