The SKIPPY filter is made out of a RUBBERMAID water trough which is very
rigid and should withstand the freeze. It is used outdoors for watering
farm animals.

Oh, I have an idea now. You use it as a filter; we use it a little
differently. We have one from the local Farm store set up as a "settling
tank-veggie filter" with a small aeration pipe splashing the water into the
back of said tank. Tons of gunk settles to the bottom. It works great! :-)
I do empty it in the winter though and leave the drain open. This way no
freezing problems and the silly birds don't drown themselves.
