it is easier to build a cover for the pond that will withstand the snow, drop the
pump in a bucket filter aiming the pump hose at the surface, drop in a 500 watt
heater set to 50oF and see how it goes. the basic problem in the frozen tundra is
how long the fish gotta go without food.
here is my pond in winter http://puregold.aquaria.net/mypond/winters/winter.htm
god... I just hate the crappy quality of the light in winter.

I started my first pond and live in Canada. The leaves are dropping fast
and soon it will be well below freezing. My pond is about 1.5 meters
deep,
but that will freeze solid by mid November here. I have a 75 gallon tank
which I hope will hold my first year fish consisting of 3 gold fish and 1
koi.
