Dave,
Thanks for the kind words!
I know that aeration may not be needed for oxygen enhancement in a pit type pond. I just want to play it safe.
I also have another agenda. Since we have a nice view of the pond from our home, I am hoping that wildlife will take the opportunity to get their winter water from the pond.
I also like seeing the "steam" coming off the open water on a cold Minnesota morning! Somehow, I think it will warm me up a little.
