You just want to make sure you have enough water in it so the liner stays in place. If you have to use a hose bib to add water to the pool, remember to shut off the water to the bib and open it to drain it so it doesn't freeze. And watch out because the hose will be brittle, too.

But it's supposed to go down to single digits again tonight! (ouch!)

Saturday night we had -3. Sunday night it was in the high 20's. This morning, less than 36 hours later it reached 56 melting most of the snow, and a few hours later DROPPED 20 degrees, and now we're due for single digits--all in just 48 hours!
