These temps have me perplexed.

I'm running mine ~10hrs - 9:00pm-ish til 7:00am-ish, depending on when I start/stop the pump.

Last couple late afternoon temp checks I've done have been ~75° on top and ~70° 10' down.

You're seeing ~12° delta in the top three feet.

Are you sure that your air pump is pumping the amount of air that it's supposed to be pumping?

Are those numbers saying that maybe it isn't?

I don't know, but it seems odd given the similarities and proximity of our ponds.
