Keep in mind that an aerated pond , while having temp differences at depth, may not have a DO problem even at the coolest depth. If this is the case (no problem to fix) then do not change what you have been doing. Fish species have different DO tolerances and can adjust by changing depth moving in and out of a true thermocline to reach a 2 way balance (DO and temps).
