Are my light settings right for the corals I have?

[glb]

My LEDs run at blue 40% for 8 hours and white 15% for 4 hours. Here's the rest of the tank specs:

The corals are fine overall but I'm wondering if they would grow more if I turned up the whites a little. Any help would be greatly appreciated!

Keep in mind there are variances in type led used, lens etc etc. Hard to base your light and setup off of someone not using same leds and light, height from bottom etc etc

For what it is worth.
30 gal, tank depth 20", light height 33" from bottom, Acros, ricordia, acans, blasto..etc etc, light reefradiance it2040. 11hr light cycle

1) blues peak at 100% midday (now I wonder how many people run full blue all day)
2) White ahh whites what to do. Well I have experimented with the whites at a few different intensity levels. 65% dulled a lot of my colors in Acros top middle. For instance Joe Acro is white in middle instead green. Old pictures showed much deeper colors when running at peak 35%. I have since reduced my white back down to 45% 1hr peak day.
3) Any light adjustments were made over weeks/months.
4) Take it from me if your happy with how things look and corals are happy leave it alone.

I would say to run your blues at 80% and whites at 20% from what I've seen most at.
If you have a controller than you can get detailed with lighting at morning to midday to evening, then I'd say you'd be getting into the ramp up motion, but only run 80% blues at high noon.
So I think your blues just need to be adjusted up, they may be on the low side.

Thanks everyone. I have a separate controller for each color so I have a lot of flexibility. The lights are about 7 inches above the tank covered by an acrylic splash shield. I realize it's hard to say specifically what to do with someone else's setup. I just wonder if my corals would grow more quickly if I dialed it up a little bit.
