This is my first post so I have to get the "I love the magazine" out of the way. A friend gave me a subscription and I look forward to getting it every month where I promptly read it in one day and have to spend the rest of the month waiting for the next issue. The question is this- should I aerate in the winter time. I am sure this has been asked many times before but I have never until today got on this site. My pond is about 25 acres with a max depth of about 20 feet and I would say an overall average of about 7 feet. I did not know if you want to have the warmer water mixing with the upper colder water in the winter and if aeration has any positive effects in the winter. I live in the center of Indiana so we get some pretty cold days in the winter time. Any help would be appreciated.
