how long should I keep lights on for reef tank?

I just got the rfk1 and wanted to set it up for how long to keep my lights on for. I have a 6 bulb t5 fixture with sps, zoas, and lps. How long should I keep the lights on for? Right now, I turn my actinics on at 1030am and off at 7pm. the daylights turn on at 11am and off at 630pm.

I have LEDs and can keep them on to 10 hours from actinic to high noon from 1-8 pm, I know its overkill but my sps really dont mind it.

I have my main lights on from 11pm to 7pm and actinics on for half an hr before and after. Should I change the actinics to an hr or extend the hours of my main lights or am I fine with this?

Do you think an hour before and after the main daylights is enough instead of the 30 mins or should I do it longer?

That's good I would say. If you can maybe a little longer. I know people who do the actinics for like 3 hours before turning the daylights on. I guess at the end of the day it's preferance. . .
