Had a fella tell me yesterday that they use empty milk jugs with a screw on lid. Fill the jug about half full (maybe a little less because you want the jug to float) and then pour in a cup or so of salt. Said it keeps an area about 3 inches around the outside of the jug ice free. Said that the cows go and drink because they think the jugs are salt blocks. Idk if this will work or not, but I'm definitely gonna try it. If they work, I may try and rig up something with 5 or so jugs attached and spaced out evenly to see if that keeps a lot of the tank unfrozen. Gimme some feedback if anyone's heard or tried this...
Thanks in advance,
Jeff
