Lighting Photoperiod

Just wondering if everyone can post their length of time they have their lights on throughout the day.

I do a Ramp up Ramp Down with a Total of my lights being on for 14 hrs. They come on at 9AM and go off at 11PM. I had some algae issues and think i'm going to decrease the time they are on. Which is why i'm curious what other members here do for their tanks.

Im at 10 hrs total (1 hr ramp up 1 hr ramp down)

That's way too long in my opinion. I use to do 12 but I now do 8 and everything is great. Same as fasiczka, ramp up and down for 1 hour.

I'd keep in mind the peak lighting intensity. And the actual intensity of the ramp too.
I have a longer day as well but to do that I have almost no light for the last and last hour of the day. The next two are very little light. I based mine on an actual time of day/intensity thing. But I'm not trying to be a champion coral grower. Mine grow totally fine and I see the tank how I want so see it at the times of day we're home to see it.

A cheap lux meter is a good tool to do this with btw.
I haven't noticed any correlation with the rate of algae growth in the near year doing this. I only get more algae growth with nutrint increases.
