How long should my lights be on?

[Reef Doctor]

What is a good time frame for the lights to be on in the display tank? I see people with lights on 8hrs, 12 hrs, etc. Some only run full power 4hrs a day. Is there a concensus on optimal?

Depends what you have? And what kind of light equipment you have? Sps, anemone, fish only,soft corals, clams.etc etc. Im running 3x250 watts hallide with 4x t5 combo. 7 hours for hallide and 8 hours on t5,I have mix sps and soft corals and clams.

With a mixed reef tank I've liked running my 2X250 Watt MHs for 8 hours and 2X54 Watt T5s on a 12 hour schedule. I'd rather be able to see the tank for an extended duration and always had good results.

I have a 75 gallon reef 3 months old, 150lbs live rock. Currently just inverts (hitchiker crabs, hermits, cucumbers, etc.) I have an ATI Dimmable Sunpower 6x54W. My lights are 4 ATI Blue +, 1 Purple Plus, 1 GE 6500K. I plan to start adding fish soon, and will eventually begin adding corals, probably LPS mostly. So are there any recommendations for my particular situation? I think currently it is running 1 hr dawn/1hr dusk with a purple plus and a blue plus, then 10 additional hours with everything on. Is this too much?

I have a 30 gallon long tank with four t5ho bulbs. I have them all on for eight hours, but my actinics will be one an hour before and after this photoperiod.

I've seen very good results with this. I only have soft corals for now.
