Coral Down Time?

Then it would benefit them to close. As far as growth goes. Lunars being for visual purpose only.

I've also noticed a difference in the polyp extension on my Turaki Acro when it comes to the amount of light. Day time=none-lunars=very little and black out every polyp is fully extended. Interesting for sure

I guess it would depend on the lights you are using for Lunars. I have read some threads where people have PAR tested blue LEDs and they were putting out nearly as much PAR as the white ones. In that case I think having them on all night wouldn't be a good idea.

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
