Thanks for the link Scott, I remember reading that a while back but had forgotten about it. And yes, actual data like that in the RC thread
One statement to note:

On the other hand, it is also very possible that some of the pigmentation that we see is due to too much light. Once a coral reaches P-max, more light actually lowers the rate of photosynthesis slightly. So a safer approach might be to look at lowering the light levels somewhat.

So obviously, growth studies are a bit difficult as I would assume the P-max varies from coral to coral. I wonder if there are any P-max values out there for various corals? Also, isn't P-max measured by O2 respiration (its been a LONG time since undergrad botany)? I would think this would be difficult to assess with corals as I cannot think of an accurate way to asses oxygen respiration under water (calling all marine biologists, do you guys know?).
Just thinking out loud...I will do my own homework when I get a chance today.
I guess one glitch that keep running in my mind is that photosynthesis, at least in plants and only from what I recall, does have a higher efficacy at certain wavelenghts and from what I understand about kelvin changes, it is essentially a change in wavelength. Has this idea been refuted or is it not applicable to coral. Also, can anyone give me a nanometer reading for different kelvins (perhaps I could have it all confused).
Take er easy
