My suggestion would be to get a timer. Run the lights from 1:00PM to 11:00pm.
Keep the shades closed in the room of the tank if you can. I dont think fish are tied to a lunar cycle in an aquarium, so what ever you make daylight should be fine with them. as long as it work out to a day and night cycle, I dont think they will care.
I got the digital timer that allows for different settings for the bright, blue and LED lighting schedules.
Hope this helps.
