I can cheat that system with the AI LED's, I can adjust blues, Royals and whites between 0-100% with 3w cree LED's giving me the flexability to make my tank what I want. Right now I have a really white "Grow" period in the middle of the day and in the morning and night I have a "Coral Pop" times when my self and others are most likely to view the tank!
I use to hate that feeling, that what I get could possibly not POP under my lighting system, I went through 4 150w MH lights on my 24g when I first got it to see what I liked the best......at 65+ dollars a bulb. I settled on the Phoenix bulbs as what I liked the best at 14k.
Only bad part about it all, is I can't find the happy medium where all corals pop right now, at the same time. But the fade in/out periods do hit all the corals at their own levels...
