Hi Jan, I'm in 7a MD.
I have been reading both discussions also not having a clue about water
layers and currents which has given me much concern because my pond is so
shallow. I was hoping to have my bigger pond done by now. I will have to
figure out if the pump can be turned down, mechanical klutz here. It ran all
last winter and it had gotten real cold here for an extended length of time.
with lots of snow that normally misses us. Joann

I left my submersed pump (on bottom) and falls running all last winter.
It
was the worst winter we have had in many years and all survived and did
fine. I am perplexed now, do I or don't I keep it running, I would think
the
water would be a better quality running and not stagnant. Pond 500 gal,
18"
deep, 1500gal Giant submersible pump. I will be so glad when I finish my
big
pond. Joann

Joann, You mention in another thread that your low temps may only be in
the
30's, if so, and if your pond runs around 45F most the time, you probably
can get away with it going. Personally I'd be a little worried about that
much current with fish that are not eating for at least 2-3 months, so you
might want to throttle it down during those months. What is your Zone?

From the discussion, and my 3' deep ponds, I think I'll continue with my
slow circulation and small air stones near the bottom in one area. ~ jan
