I have just recently put my lights on a timer, they are on from 11:00 am to 9:15 pm. Anyways, school is about to start and my lighting schedule is probably going to have to change. What time do you have lights come on and when do you turn them off? I am so confused, and i cant think of anything that will work. by the way, I have to leave at about 7:00, and sometimes I'm not home until about 5:00. The tank has fish, so I have to feed them sometime.
