How long to leave light on

  • We are currently upgrading MFK. thanks! -neo
Depends, like do you have plants or not? Most plants require certain amounts of light. It's also possible to not even turn on your lights.
 
I'm lazy sometimes in few of my tanks, I just leave it on 24 hours a day for weeks-

some of them are planted tanks and some are not- I have some tanks on manual timers for 15 hours a day when i'm awake, I don't see a point into having tanks that you can't see for few hours a day give or take.
 
Well it does depend on if you have plants or not, but I use timers so I can keep the lighting stable and not keep the fish all off balance with the "days" starting at all different times and stuff. I put the timers for from 9 am to 8 pm for the light and the bubblers for from 11 am to 8 pm, so that I'm still able to sleep in ;)

lol i hear ya :D
 
my planted tanks have the lights on 12hrs/day . . . I have minimal algae problems, usually just beard or hair algae . . . I do keep siamese algae eaters and small plecos in my planted tanks, which helps . . ..

I was just wondering how long do you guys leave you aquarium lights on? :confused::confused::confused:

Read somewhere that you shouldn't leave it on for more then 6 hrs a day, but was watching this video on the internet (bored) and it said you should leave your lights on 12 hrs a day to help kill algae.
That is ludicrous! I only turn my tank lights on when I feed and for four hours after the sun goes down. Where did you get this info ?

just thought of something. LFS there are lights over the tank on all the time. How come they don't have an algae farm?
They pay someone to get on that little ladder and scrape the algae. Also they pay this person to leave the dead fish in the tanks and they are typically incapable of giving you straight answers that don't involve spending hundreds.
