I have a 1 acre 16 ft deep pond that I run a bottom aerator in the center of year round. We had a recent very cold spell and the aeration line coming out of the compressor sprung a leak, and before I could catch it the water above the aerator froze over. So now I don't know how thick the ice is there and whether or not I should continue running the aerator underneath it. I do have a dock and I'm wondering if I should just go out on it and poke some holes in the ice and if that would be enough to vent the pond. I'm guessing continuing to run aeration underneath a totally frozen pond is not good for the fish.. We are not expecting any relatively warm weather in the near future.
