We start out about 7am with our atinic blue, around 9am we turn our daylights on, at about 1pm we turn the mhs on, at 5pm we turn the mhs off, after I feed at 8pm I turn the daylights off and at about 10pm I shut the atinic off. Kind of a long process, but I'm home all day, and everyone in the tank seems to like it so if it works I say way change it. Later Lisa
