This is going to be more personal preference than anything. Although some corals do like certain colors, specifically some corals like a bluer coloration due to the depth they are naturally found, but since most people have such an assortment of corals from all different areas of a reef, it's not as big an issue as you think. The lighting is sufficient so color is up to you
Heres what I got going on my 4 x 54w T5 fixture: from front to back, I have one of the "purple bulbs" one of the Midday bulbs, one of the blue bulbs, and last, another purple. Forgive me, I forget if the blue or the purples were the actinic + bulbs and don't recall what the other one is named. This combo gives an overall coloration closer to that of a 20,000k spectrum, while what you have there is going to look really white.
Also, depending on the corals you have, I've heard several reports that claim that a midday spectrum, closer to 6700k is better for overall stoney coral growth, vs. a 10,000k spectrum or higher that you are getting with the aquablue + bulbs. Although my corals had nice growth when I kept those bulbs over them, I like the results from the miday better. It's just more yellow in appearance and without sufficeint actnic supplementation, the tanks going to look more like a freshwater tank in my opinion.
