As far as how they work, the timer just controls an on and off function? Does it control an on, at a certain %, and automatically ramps up to a higher %, and goes back down before it shuts off?
I'm assuming there's no "moonlight" feature on it? The tank lights are completely off when the timer shuts them off?
Do you use anything extra for a moonlight effect?
No these are not ramping. There are 2timers one for whites and one for blues. I do not supplement for moonlight.
