Concrete Holding Tank
I recently built a cottage and have a 1650 concrete holding tank. My full line is 54". I recently had it emptied and so there is not much in there but it seems to be freezing. Anything I can do to prevent this? Something I can add? It has been really cold here. I likely won't have to empty it for a month or so but was just wanting to keep it liquid.
Thank you
