Hmmm, so ... what I gather from this is that at 12" the 10000K bulb was better than the Radium even without the SonAgro ballast on the 10000K, and that is even taking into account the 10000K was further from the water surface??
But at further depth, the Radium seemed to "attenuate" (for lack of a better term) less than the 10000K, ie., the deeper into the tank, the better the Radium got over the 10000K?
??? :? ???
From what I understand, PAR = growth, but higher-K = coral colour, so I guess one neat experiment to try, would be take two frags of the same coral and see how they compare after a month, several months, one year, etc. ... ?
