In past winters I have left air stones in the pond to keep a hole in the ice allowing deadly gases to escape the ice cover.
Last year I left the pond running including falls and all. The entire waterfall and pond iced over but the water continued to run under the ice sheet. It was interesting, you could hear the waterfall but couldn't see it.
My question is, with the water moving under the ice are the gasses being release at some point in the water flow? Like some small open water spots in the covered skippy filters?
Or should I still keep a hole in the ice of the pond with air stones, even if I leave the pumps running.
