Ted,
Thanks for your input. Yes, our pond is stocked. We have bluegill, bass, golden shiners, creek chubs. I have had the pump on 24/7 because I have read that the fish need light and also 02. I dont know if our pump could pump through 4" of ice. We had almost the same situation last year, and left our pump on. We lost only about 20 bgill and no bass. Kay
