How many hours per day do you run your lights?

I just cut down to 10 hours from 12, I'm hoping to see if this cuts back on some of the algae growing on my class. How long do you guys leave your lights on? And do any of you oxygenate your water once the lights shut off? I'm thinking of adding a small airpump to do so once the lights shut off.

12 on, 12 off. I give them a little extra light since the sun hardly ever hits the tanks.

10 hours on with full 154w over a 30g. My 2.5g gets 8 since its harder to regulate.

I raise my sword in the air in the battle against clado. I have been beaten in this battle but the war is not over. As my wounds heal I amass another army, an army with many legs, an army of Amano's......

I thrust my tridant into the mass of medusa like staghorn. I am wounded but I refuse to take a knee.

My timer is not working well, so I aim for 8 to 10 hours a day, usually hitting close to 8. I have horrible luck with timers, always the Intermatic (?) brand.
