Pond Boss Forums AERATION Systems questions 8 acre pond at 10,000' - lots of aeration ?s

All I can say is I don't know. I suspect that it is like Bill D said, not enough sustained winds to keep it open. It is hard to quantify tho. When we are there in the summer, the windmill would spin everyday. How long does it need to spin to open a hole right now, I have no idea. The last time they went up was Christmas eve. There were thin spots in the ice but no holes.

I thought the pressure in the airline would keep water from backing up the line?

Thay are going up again next weekend. We will see if anything changes.
