Overwintering goldfish in Manitoba

[maron6977]

Probably doesn't get as cold here but - I just pull pump & filter out , let pond freeze over . Fish hibernate, ice forms barrier from weather & will insulate fish if deep enough. Don't keep water moving , otherwise water temp will drop lower than 0 & not freeze . Just make sure pond is deep enough to get warmth from under ground surface . Mine has only frozen 6" & is 2' deep , -15c
