Pet Forum / Aquaria / Goldfish / March 2008How Long Should I Leave On My Tank Light?
Should I just turn it on at night? > Should I just turn it on at night? I have my tank lights on a timer. They come on at dawn (more or less), off at dusk, or about 12 hours. If you turn it on at night, basically you're forcing the fish to be in light all the time. I'm not sure what that might do to them, but in the wild they experience darkness at night just as we do. But maybe the more experienced fishkeepers will have different advice. Gail Thanks Gail. The light is off right now, as my tank is near a window, and it's sunny out right now. I can't see putting on a tank light in a sunny room in the day, but I want what's best for the fish, of course. Won't too much light promote algae? > Thanks Gail.

Yes too long of a light schedule will definately promote algae. Unless you have live plants your not going to be held to a sceheduled affair with lights, but its still nice to have lights go on at a certain time and off at a certain time and lights should never be left on over night. Adjust the lights to your viewing pleasure and schedule if your not with live plants and don;t go past 12 hours max with them on. 12 hours is pretty well what any plants would ever require anyhow and is a fair rep[resentaitoin of typical daylight lighting hours.........I know you probably do not like it if someone arbitrarily turns on the light when your asleep, so once the lights are turned off leave em off unless its absolutely necesary to turn em on as the fish will alsoappreciate not getting shocked by the lights getting turned on after they were already in bed so to speak. Just buy a simple cheap timer at Wal MArt for about 5 or 6 bucks and plug yuor lights into it and forget about it........Timers are great for things like this and well worth the couple of bucks you can get one for. > Thanks Gail.

I should have mentioned I have planted tanks - lots of live plants. Which is why I need the light. I suppose without live plants you could buy an algae eater, but I don't know that much about those fish. I think ExPat has a great response and I agree with that post. Gail > Should I just turn it on at night? Hi there LuAnn. You can't leave the lights on during the night because fish need a day / night cycle just like humans do. Fish go into sleep mode when it's dark. When the lights are on all the time they think it's time to be up and hunting for food. It's puts a lot of stress on their bodies when the lights are left on all night. |
