Its very fun to have found this forum, especially for the trials and challenges for us northern climate ponders. I'm looking forward to browsing this forum and sharing my experiences. No ice on pond yet but fish are slow and settling into their winter hibernation. My new aerator is hosed from inside home for warm air and excited to see this 2nd winter with a trouble free aerator hose. Freeze problems in line before I buried the hose underground. Good luck everyone overwintering.
