Last time I did calculation of how much the air bubbles lifted water and how deep my system was and what its CFM of air was it came out that I was just about at turning over my whole pond in 24 or 26 hours if I recall correctly.

But even if I'm turning over the whole pond, I still notice that there is definitely colder water deeper than say 5 feet (just by how cold it is when wading in to do maintenance)


At the depth where you are trying to keep the pond "cool"?

Here is a wired indoor/outdoor thermometer that has a 4.8' long wired lead.
