What kind of lights? Length of time (what you call photo period I assume) is almost immaterial. The zooxanthellae in coral do photosynthesis for 4-6 hours and then shut down. Longer daylight doesn't hurt the coral, buy it doesn't help either. The longer time frame is for our benefit, not the coral's. If you have leds, what make and what power levels are you running. That's way more important than length of time.
