New member - read through the posts but still confused on aeration in the winter time. I was advised to keep aerator on through the winter to keep pond open and prevent a freeze of the pond. Located in Missouri and pond will freeze over the top - like last year. Outside temps will get into the teens and rarely into single digits. Smallish pond - 4 years old. 1/3 acre and 14’ depth. Have not taken temp of water at any time. Bass and blue gill pond for kids to fish. Any reason not to keep aerator on other than electricity cost and wear and tear. Thanks for advice.
