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.

It's only been a week since I got it but I am running a Tek 48" 6 bulb fixture.

11:00AM - actinics on
12:00 noon - main lights on
9:00PM - main lights off
10:00PM - actinis off

11 Hours in total

Mainlights and actinics on at 11 am. Mains off at 9pm actinics off 11pm.

Actinics on at 9:30
Daylights on at 12:00
Daylights off at 9:00
Actinics off at 9:45

Got a question on lighting in general here (http://www.canreef.com/vbulletin/showthread.php?p=306259#post306259).

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.
