you don't really NEED moonlighting, its mostly to be able to view your tank at night i believe... those blue LED's just don't provide enough light for an benefit to the fish tank.
zdthompson you should also start your lights up with just the blue light on, know what i mean? so basically,
blue light on first (sunrise)
both lights on (day)
blue light on (sunset)
no light (night)
Also you dont need to run your lights for such a long period of time, you may run into algae problems if you do. However, if you haven't already then i guess you're ok. Avg. time to leave lights on (for nano's anyway) i've seen is about 6-8 hrs (total for sunrise, day, sunset)
