I've tried just about every combo over the years, the best coral growth came from a 6 hr on/off cycle (two photo periods in a 24 hr time frame) but it seamed to stress the fish more. anything over 6 hrs but not more then 14 hrs has given me about the same results so it's best to determine what's best for YOU, what time of day are you and your family home to watch the fish? that is as good a schedule to set your tank around as any.
as for moonlights, mine stay on 24/7, they automatically adjust in intensity according to the phases of the moon and to tell the truth i see no benefit to having them other then it's nice to view the tank at night when they are in a phase thats intense enough to do so. i used to have them set on a timer opposite the lights, but the 24/7 works just as good and being LEDs they have a lengthy enough life expectancy it's not necessary.
