You opened up a big can of worms. There are all kinds of recommendations for combos. It will boil down to what you prefer.
I like a bluer tank so I run more of the blue spectrum. Such as ATI Blue+. If you already have a super actinic I would say run 1 of the t-5's as another actinic and then concentrate on a mixture of 1 daylight, couple of very blue spectrum, 1 red or pink, and then the final bulbs near the daylight such as aqua blue +. That's just my opinion tough.
Have you surfed RC to see Grim's recommendations yet? He also has his own web page.
