How long do you run your lights?

[Fieryfrog]

I am sure there is are a bunch of threads out there about this. But my head hurts lokking for them.

So, how long do you run your lights? I am sure I run them WAY too long. I have the blues coming on at 6:30am and going off at 10:00pm. And my regular lights come on at 7:00 am and go out at 8:00pm. And am sure this is leading to an algae issue.

LEDs, 8 hours, no ramp up or down. Moon LEDs for 4 hours on either side of normal lights.

Hmmm, apparently I am not running mine near long enough! Isn't algae a issue with lights running that long? Or is it combated through good husbandry?

Blues 12hrs and whites 4hrs. I have some film algae but my snail and hermits takes care of it. Algae is also dependent on other factors such as amount fed, bulb age, etc.

This is my concern. I worry about algae.

 

[Acro]

I don't have any problems with algae

 

[ReeferRookie]

Im terrible i run blue leds all night and my actual light is only 10 hours

Well I took a chance and changed. Being today is Saturday I could turn my lights on longer then normal. So far I have noticed everything opening up more, and my carpet is bigger then ever before. So maybe it is worth it to run lights longer then I thought. Ma just need a better/bigger cuc to help combat any nuisance algae.

Yup. My crews do a good job. 1 fighting conch 1 sand shifting star 5 hermits 5 turbos

9 hours. VHO's a half hour, then blues come on for half an hour, then whites on 7 hours, whites off, after a half hour blues off, another half hour and VHO's off.

12 hrs hydra LEDS. 80%-90% blues 20% White 30-50% everything else.
