rintx,
Continue to water. Freeze should not be a problem. You may see some isolated surface pops, but the rough surface will be covered with plaster of some sort.

Congrats on starting your new pool! Who is your pool builder? You may want to ask your pool builder about watering. When we built, they said it is more important to water the gunite when it's really hot outside so maybe you don't need to as much with the cold we've been having. I am NOT a PB though, so that's who I would ultimately ask, if I were you. Ours sent us watering instructions that were very specific. Good luck to you! Do you have any photos to share?
