this may sound like a stupid question but i'm curious. how do people keep their outdoor pond fish from dying in the winter. we have cold winters in southern illinois, nothing arctic but cold, definately below freezing a lot. i figure heaters but what do you use with a foot or two of ice or snow? i like outdoor ponds but i'm afraid it's impossible with cold winters. thanks for any and all advice and info

I have no clue. I live in San Diego and it never gets that cold here. I have a 800 w heater in mine and I cover the pond at night when it gets cold.
