Ok, I think I understand. The blue lunar and white leds work together? So I could put them on a timer set for an hour or so before the main light comes on and then an hour or so after to simulate sunset and sunrise? The main question I have is that the all the leds, blue and white, work together at the same time? Thanks.
I never thought about that. A true dark time. When you think about, the moon is not always out and full every night. Thanks again. I will take all this into consideration and come up with myfinal plan. Not to get off track, but do you let protien skimmers run 24/7 ???
