I definitely think it is a good idea to have complete darkness for at least a few hours.

I wonder how much PAR actual moon provides on the reef? Anyone know?
Yeah, I didn't even think of that. I have 4x lunars. Not sure of the watt though. Maybe a good question for Evil. I'll post the question to him
