I live in northern California where the winters can be freezing at night for a few nights and the days can be in the 50's or 60's. I did not do anything to get my pool ready for the winter during the past 2 winters. We only had the pool for 2 winters. It went down to 29 degrees for a few nights last winter. All I did was to put a piece of mil 6 plastic over the pool equipment since ice was forming. Should I be doing more than that?
I have been reading on this forum that I should have the pump running during freezing temperatures but I didn't because I did not know. What should I do differently for the pool when the temperatures are freezing at night and I don't close it for the winter? I intend to continue to test the water. No pool cover was ever made for the pool since it is a free form pool so I can't cover it. Thanks.
