Well if my thermometer works the water was still at 62 this morning and that is with air temps being below 30 since midnight. So I am thinking my little heater is working pretty good. And I may just have bought me another week or two of time.

I had thought about getting a second one but with them being 1000 watts I am sure they are pulling some juice.

Plus I tossed in a few pellets about 30 minutes ago and I noticed some fish popping them so they must still be active for now.
