Out of curiosity, do corals generally tend to grow slower when under heavy "display" actinics? I know there are so many other variables, but in a general sense, assuming other variables are equal, corals are under those very heavy actinic lighting(towards the 20,000k levels)do they grow slower than when under much more balanced white daylighting(closer to 10,000k)?

I can't point you to anything definitive, but years ago it was said that corals grew fastest under 6500K (yellow/daylight) lighting, but that they tended to brown out. They colored up better under higher Kelvin (e.g. 20,000K) lighting.

At about 11:20 in this video Jason Fox talks about using all actinics. I found this very interesting.

His rationale for keeping it blue is a big generalizaton.  However, it seems - based on what I've seen anecdotally - that blue/actinic is what's responsible for all the cool colors we see in the aquarium.  (which aren't as common in nature)
