So I use to run my light cycle for 5 hours a day with the actinic's coming on 30 min before then turning off 5 min after the main lights come on. The actinics would then come on again 15 min before the main lights went off and the actinics would turn off 30 mins after the main lights went off.

I then changed the light cycle to run 7 hours a day with the actinics running the same as above. Today I changed it back to the 5 hours a day since I don't get home until 5:30 pm and no one is here to enjoy the tank during the day.

My question is how long should the tank lights be running so that the corals get what they need? Also what are some light cycle lengths you guys run?
