GIGGETY-GIGGETY!!
joesandy... i live close by as you know. you have a decent sized pond. and if i recall, a fairly small fishload. your hole freezing over for a week or 2 shouldnt be a huge problem. my pond is only 1200 gals. i do absolutely nothing for the winters, and until this year i have left fish in the outdoor pond. last year, i left 120 fish 2-3" long in mine. no pump, no aerator, no hole, no nothing. now i'm not saying its not a good idea to use these. just saying i never have and i've never lost a fish. so dont panic.
