Average time lights are on

How long do you leave your lights on per day.

I run mine about 8 hours and I think it's to long

[jeb102385]

I keep mine on 4p to 11p. it alll depends on how many plecos you have and the wattage of the light. More light will result in lots of algae. If the light is weaker or you have plenty of plecos you can leave the light on longer without any ill effects.

I leave my kalambo lights on for 10-12 hours. No problem with algae and I have no plecos. I have GLO T5 lighting too. My trophs graze on it.

I have my lights on 3 hrs a day rest of the light is just room light onto the tank

I went to the Marineland double bright LED's and the brown algae is a lot worse.

[LordBarron7692]

My lights are on 12+ hours a day with very little algae but I also have petros and and a couple of plecos in the tank

[mnemenoi]

Depends on the tank, lighting, stock. Usually 7-10 hours on average

Mine are on from about 5pm until midnight. Not much algae but lots of bristlenose!
