I don't know about the algae out break Lorenzo, I think that has something more to do with excess nutrients over to much of a blue spectrum. Besides algae grows faster at a lower spectrum (around 6700k) while actinics occupy the 20K spectrum. I'm running the 8 fixture Tek 5 over my frag tank now with 3 actinics, 1 figi and 4 day lights and I love the color it brings out in my corals. The actinics add a "pop" to the florescent corals and I my favorite time to watch them is at dusk/ dawn for that exact purpose.

also sounds like you have a good source for Giesemann bulbs. personally this is what I would do:
pure actinic
Fiji purple
aquablue+
actinic+
aquablue+
actinic+
This set up you will still get that blue glow from the tank. Stay away from to many pure actinic's. This is second hand info for me and i have no intentions of finding out but they cause crazy algae outbreaks.
I am starting to stray away from the 10k/midday bulbs. to me they are to white and running to many has been known to bleach out corals. Your on the right path with the aquablue+ (Giesemann or ATI) as they are similar to a 14,000k bulb. for an 8 bulb fixture, i would run the same set up as i listed above but add 1 more actinic+ and aquablue+
