Aquaray & moonlight simulation

[ivolach]

Is there a way to get the illumination brightness go down to 0% with the moonlight simulation (at new moon phase when there is practically no moon)? The lowest I am able to go is 3%.

My setup:
Profilux 3ex
Profilux LED controller-1
Aquaray 100.

My settings:
Illumination 1 - set to 10% between 8:30PM - 6:30AM
Illumination 2 - set to 15% between 8:30PM - 6:30AM
Both channels are set to moonlight simulation.

Moonlight simulation is set to 8:29PM-6:31AM

L5 - set to illumination 1
L6 - set to illumination 2
and yet, both L5 & L6 stay at 3% between 8:30PM - 6:30AM.

The way I read the manual, they should be at different level since the moonlight simulation is calculated as moonbrightness%*max brightness at the relevalnt time.
