Marie, I would agree only if the other corals around it were acting the same. But this one is right up under the light, maybe 6inches under waterline. I have a pink milli, same height on the other side of the tank, it's doing incredible, holding it's pink very well. I'm not saying lack of light isn't it though, because it was in the same spot under the 400w. And you're right, one SOL unit is not anywhere near a 400w MH bulb in intensity.
Sounds like I need to supplement the LED with MH bulbs
