What light spectrum % do u ude for coral growth?

[HexaReef]

I have a 3 channel full spectrum led light. Each channel (blue, white, red/green/uv) can be adjusted. What percentage of each do you find is best for coral growth?

I use the Kessil AP700 which has a spectral control that allows you to adjust the level from white to blue and add red and green to it. When I used my seneye to measure PAR/PUR, I found that PUR was slightly higher when blue was a little deeper. So, you can do well with more blue mixed with white. My red and green are about 15%. Red can cause algae to build up, so beware.

Right now im running 40% blue, 60% white, 20% RG. That a good mix?

Personally, I would switch blue to 60% and white to 40%. it's really based on the look you like but your PUR will probably be a little better.
