but it is buried in the earth, so rather than a 1500 watt heater, a
300-500 watt heater and plastic over the top is all that is needed.
besides, those stock tank heaters are expensive and dont last very
long. titanium heaters last nearly forever. Ingrid

Question:

I have a 6 foot by 2 foot by 2 foot pond that was formerly a cattle trough.
It has a liner, fountain, and is buried approximately 20 inches in the
ground. I need advice on the best way to help my goldfish and koi survive
the harsh Chicago winters.

Thanks in advance

This is a stock tank, I think it calls for a "stock tank heater". ;-) After
all, cows & horses have to have liquid water even in Chicago. Course you
saw the power bill mentioned. So covering it would really help. ~ jan
