I used to have a pond in my old house and in the winter put a Trough heater in it to stop it from freezing over and the fish stayed out all winter ... I did not have a nice filtration setup like you do but a friend of mine built a nice pond and used the skippy filter and said it worked well ... but with your setup dont you think a submersible heater in the Skippy filter at about 60 degrees farenheit ought to keep everything running year round ?
You will obviously still have to take the plants in but may save some space by not having to take the fish in each fall ... plus save you from draining it in the fall
I am thinking of building another pond in the backyard of the new place.
food for thought
