Update! My mum and I woke up at dawn to chop up the ice and add more steaming water into the skimmers. The dark spot at the far end (deep side) shows us that our strongest jet is still working. We still have power, but if that gets shot, the pool is “toast” (for lack of a better word in these frigid temperatures.)
Side note: This weather is delaying Covid vaccines. I was supposed to schedule my 2nd dose this week, but all time slots were pulled.
