thanks for the response. i also brought my filter inside to overwinter.
it was a couple hundred dollars and i didn't want to run the risk of
have it ice over and crack. the filter has been with the goldfish
inside so it should be ok.

i'll give the pond a few more weeks until it's over 60=B0F all the time
like you say. it'll be somewhat tricky bring the water temps down
slowly but i'll figure out something. i know it's much harder for them
to go into cooler water than warmer and don't want to loose any of
them... even if they are $0.25 feeder goldfish.
