Hey Orville,

Most guys here will tell you if your going to choose a 12 hour shift it should be at night. Why?

Well that's when your pond has more D.O. loss then at any other time. Your plants are not producing any D.O. at night as a matter of fact they are putting off Carbon Dioxide which isn't good. During the day they will put off D.O. with the sun hitting them.

So if it were me I would run it at night if I had to choose a 12 hours shift.

The only difference between a rut and a Grave is the depth. So get up get out of that rut and get moving!! Time to work!!
