How bright do you have your moon lights? Do you have any pictures?
I have 2 12" cold cathode florescent tubes for my moon lighting and when I turn them up all the way the tank is very well lite. So lite that some of my fish (mostly my tang) gets stressed out and wont sleep. To keep the fish happy and sleeping at night I keep the moon lighting at less then 1/4 the full brightness the lights can go. This makes the tank not very well lite.
Tonight I will take some pictures to show you all how bright my tank is at night and how bright I can make it.
Another question I have that is not about lighting is. Should I turn off my Seio pumps at night to give the current a rest? The ocean is calmer at night then in the day so shouldn't my aquarium?
