How long does everyone keep their lights on and why?

I want to keep my lights on for as long as possible but not too long to help algae growth. 8 maybe 9 hours or more but I'm not sure what the average time is for everyone.

Thanks.

 

My actinics are on for 12 hours and my 10,000k's are on for 10. 4 LED moonlights on all night.

 

10 antic 8 halide with 1 hour start up time and shut off time between antic and halide moon on all night

 

10 hrs on the T5's. 7 hrs on the MH's. T5's on 1.5 hrs on each side of MH's. the fuge light on 20 hrs a day.

 

Actinic on 12 hrs, daylight on 10 hrs. They are power compacts.

 

I logged on specific to search for a thread on THIS topic. Couldn't have been better timed.

I have my actinics are for 15 hours and my 10K's are on for 9.

I am battling green hair algae and not getting the coraline growth that I want so I was wondering if I needed to do less light. What is enough for corals and not so much to induce algae?

BTW, tank is 2.5 months old, water params are good.

Moons on 1 hr either side of T-5's. Eight on T-5's, 10 Total.

 

Your tank is still maturing...You are going to go through algae blooms. It is just something that happens...Not to everyone, but it happens. I to this day believe that algae is due to whatever was in the live rock you purchased. Changing your light schedule is a temporary fix IMO. Until the algae uses all of the fuel available, it will continue. Run a good Phosban reactor, Skimmer, and keep up with your water changes. Don't overfeed, and then just WAIT IT OUT> You cannot stop mother nature, just help her. It will pass. Mine took almost three months to get through Hair Algae. I haven't seen it since.;D

 

I have my dawn/dusk on for 12 hours and daylight for 10 hours. I am hoping to replicate the tropical light schedule since most if not all of our corals come from the tropics.

 

What are dawn/dusk lights and daylight lights? What is the difference?
