View Full Version : T5 Daily Lighting Duration
If your tank is lit ONLY with T5s, how long do you keep them on each day?

4 outside bulbs come on at 10:30am
4 inside bulbs come on at 11:00am
Inside bulbs off again at 10:30pm
Outside bulbs off again at 11:00pm
So I guess 12.5 hours :)
But I should mention, my lights are also programmed to turn off between 3:30-4:30pm (considering making it 5:30pm). Part of an experiment to reduce algae growth/disrupting its photosynthetic cycle.

I am 12 hrs, 10-10. but once cycled and livestock in, I'll see how 10-11 fairs with them
I figured I would get more varying answers! Mine go on 10 am, and off at 9 pm. So I have 11 hours.
