That is the question...
I live in Charlotte, NC where typically it won't get cold enough to freeze my pond, but we do get ice storms that can cause power outages. My pond is between 1000-1500 gallons (I plan to meter it in the spring after cleaning and refilling) and I have a submersible pump with an external filter that discharges into a small "pond" area and then over the 2 falls back into the pond. Should I plan to shut the system off this winter? What if I go out of town over Christmas and we get an ice storm that shuts off power and the water in my tubing freezes...will is blow the pump when the power comes back on?
I had planned to just leave the pond running and cleaning out the filter like I have done all summer, but I hadn't thought about all this other stuff yet.
What kinds of things would I have to consider if I were to shut it down? and is it worth that where I live? Am I just being too cautious because this is my first winter?
Any help or advise is greatly appreciated. Thanks!
