How Long Do You Keep Lights On?

[Blondielovesfish]

 

I keep mine on for 8 hours each day, on at 8am and off a 2pm on weekdays and on at 12pm and off a 8pm on weekends.
 
I have vallis, hygrophila (stricta) and java fern. I also dose flourish twice a week.
 
EDIT: Adding in what plants I have.

8am - 2pm is 6 hours lol .
 

 
That's what I meant LOL

I keep mine on for around 10-12 hours a day, only because I just got new plants. From 7:30 AM to about 6-7 PM is normal for my tank

5-10 hours depending on my work schedule, or when i'm going to bed. Id say on average about 8 hours a day.

8-10 hours in the four footer, depending on whether I have moved or added plants.
2-3 hours in the betta tank, but it sits right by a table lamp, that Mrs. doodle keeps on most of the day.
Mostly easy growing plants, dose Flourish twice a week. No CO2.`

Mine is on for about 12-13 hours. On at 6-7am (when I get up) and off at about 6-7pm. Plants and fish seem to be happy.

thanks to all who answered.
lots of answers here, as fluttermoth said "6-8 hours" looks about average. a few 12hrs (I wish I could have mine on that long). gruntle, 13 hours? you legend

.  
 
my max is 8 hours to start a little algae build up enough for my nerite snails to feed on.

It's a fairly dark room and just a standard fluorescent tube. It's just easy for me to switch the light on in the morning, feed, do a headcount, and go to work. Then come home from work, do a headcount and switch off.
 
After a massive house renovation later in the year the tank may find itself a new home in the lounge room so maybe no need for such a long light interval.

Mine are on for about 8 hrs. I've heard if you leave your lights on all day your fish's organs will outgrow the fish and shorten it's life, so I'm really paranoid about my lights being left on.

Well no need for you to be paranoid, since it's not true
What you're referring to is keeping a fish in a tank that is too small. This is called stunting.

Think I must be getting more light in my room than I thought. If it wasn't for algae I'd have my lights on around 12 hour mark .
