I have a 9000 gallon steel tank epoxy coated inside, and it is 9 feet across and 20 feet tall,
I know it freezes, up on some of it, I have done two things, one I put a bubbler in it, and painted it a medium brown, so the solar heat would help it,
we were near 0F at nights and below freezing during the day for a few weeks, most ever year, for the 10 years we have been using it, I am sure the out side has a few feet of ice on it, and my float needs replaced, (guessing the cable/cord) has been damaged from the ice falling or changing levels, so I know that ice has built up in the tank but since the water is moving and being pumped in and use out of it, it I have never had to abandon it during the winter months, on the piping I have a tunnel under it that I take the water out of the center of the tank and from the bottom,
I do hope to some time build a insulated enclose around it, with a solar type collector on the south on the south exposer, to add some more heat for the winter time.
