Winterizing my pond

[deeni0z]

do you need to winterize your pond if you live in southern california? it gets to be around 35 degrees fahrenheit or so on the coldest nights, sometimes colder but ti's rare.

How long of a winter do you have and does your pond ice over ?

I have just had my pond for a few months and am now getting it winterized. I brought in my fancy goldfish but wonder if I can leave my comets out all winter if I use a de-icer. It is a small pond 4x4x2 with a stream and waterfall. Is it best I shut off the waterfall which feeds the stream and then just add the deicer?

Winterizing my pond is not an issue in Aus.
But I'm curious as to if anyone is using an existing heat source and transferring the heat to their ponds .........I use a circulating system to cool my aquarium by circulating piped water through our house rainwater storage tanks........and I wondered if anyone was doing the opposite and warming their pond by a similiar methods......maybe from a well or dam.
