To be honest with you Ryan I have not attempted to see if their is a temperature change from bucket to bucket but I expected there is one due to cooling power of evaporation. Or so say the texts. Perhaps someone else here can explain it?

I'll see if I can take some readings tomorrow and report back for a comparison. My best temp sensor is on loan with my D.O. meter but I do have a PH meter that also does temp.

Do you have the newest Pentair Aquatic Eco-Systems catalog? If not on page 279 they show the following for D.O. saturation for buckets they sell:

Inlet water 57 % oxygen 110 percent nitrogen
Outlet water after one segment 76 % oxygen/ 106 % nitrogen
Outlet water after two segments 84% oxygen /104 % nitrogen
Outlet water after three segments 89 % oxygen / 103 % nitrogen
Outlet water after four segments 92 % oxygen /102 % nitrogen
Outlet water after five segments 94 % oxygen/ 101 % nitrogen

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
