Thank you for letting me join your forum. I find that you never can have enough info about pond keeping and caring for fish and plants. I have had a pond now for 4 years and learn something new every year. With the spring thaw now finally under way, I was really excited to finally be able to see images of our fish under the ice. This was short lived, only to find that ALL living life no longer exists in my pond, do to a pond de-icer that has failed. People may think I am pretty strange, but I am really devastated, we have had these fish for 4 yrs now and the majority of them had their own names as well as the frogs. So I guess maybe now I can post my first question. Does anyone have any idea how to prevent this from happening again? The only thing I know to do is have 2 heaters in case one fails. I am open to any suggestions.Thank you Sherri
