Just want to know what others in northern CA are doing to keep the pool equipment from getting frozen. I was running the pool pump from 4:00 am to 8:00 am but now I wonder if that is enough. This cold spell drops the temperature to the 20's for a few hours at night and it is going to continue for a few more nights. The weather report says it will be 32 degrees tonight by 8:00 pm. Should I run the pool pump as soon as the temperature goes down to 32 degrees? That means that it will run for at least 12 hours since the temperature will stay below 32 degrees until the following morning. What about the waterfall? Do I have to leave them on at the same time also? Thanks.
