Just an update.... Pump and diffusers working amazing. I have the timer set from 8pm to 1am for now. Not sure if that's to long or to short but I lost about 18 inches so far from evaporation and the water gets pretty warm and still.
I'll have to run it 24/7 in the winter to avoid freezing.
Special thanks to JKB and all others for the advice.
Loving my new pond! Just wish I had a 4 season stream to feed it!
