Quite possibly. Though in general any of these colonies will hang out for 4-6 weeks in apparent perfect health, and then RTN in a couple of days, or STN over a period of a couple of weeks. However, frags of these same colonies seem to do quite well in a tank that I have that's run with T5HO. Moreover, many of these colonies are "second generation" propagated from the initial maricultured ones from Indonesia under MH.
Nevertheless, it could still be a light acclimation issue. It's unlikely to be intensity, since the PAR measurements come out quite closely. But it's certainly not impossible for it to be a spectral issue. Quite a number of these colonies color-shift under the Radions.
