What light percentages do you recommend?

I have Al Hydra lights in my 200+ gallon tank. The lights are about 10 inches above the water level. Here is my current remote set up. I want something that will help coral growth and health. I'm not sure what levels should stay lower, and which ones should be up.

I've set my hydra up for more color than growth, and I've been impressed how my corals have colored up. Basically everything looks better than it did in the LFS and other people's tanks I got the corals from. I start at 20k spectrum with 100 on UV, Violet, Blue and RB and 17 on green red and white. Then I go to a 14k spectrum gradually as the day progresses. The peak it hits at 'noon' fish time is still 100 on all the blue/violet/uv and then go up to 40 in red green and white.

Thanks! Isn't 100 for uv way too high? That kinda scares me.

Its been running that way for about 9 months, and everything is thriving. I do only have LPS, but that shouldn't make too much of a difference.
