Adviseable Hours For Lights?

What is the adviseable amount of hours for the lighting of a small reef tank

I get up at 7am and usually put lights on then and got to bed bout midnght and put lights out then

17 hours seems a long time to me and could that actually be detrimental to the coral

Yip 17 is a bit to long mine turn on at 14:00 then go to moonlights at 22:00 then all of at 23:00 to much lighting can cause algae issues 8 - 10 hours is the norm and corals like routine so a timer would be advised

I have my lights on for 12 hours, 9am - 9pm. I would love to have them on or a shorter amount of time, but it's not very possible with my schedule and with feeding etc.
