So, if the corals aren't darkening up, don't use it at all. I would quit using the Spur2 until you can figure out what is going on since Spur2 is only for your own viewing pleasure. From my understanding it isn't for the health of the corals at all.

Did you keep SPS corals successfully before you moved to the bigger tank?
