Thanks Tracy. How far did you have to run from the pump to the pond? I've got to go roughly 900'. Plus into a pretty big ravine and back up a hill, then over to the pond. I keep thinking water will settle in the hose. I don't have a big ice problem, so I don't think I will run it in winter, but who knows.
I was hoping it would help lower water temps.

RES, YP, GS, FHM (no longer), HBG (going away), SMB, and HSB (only one seen in 5 yrs) Restocked HSB (2020) Have seen one of these.
I think that's about all I should put in my little pond.
