Dallas Metro area pool owners out there? My spouse asked me if I know how to "winterize" our pool and I told him "no". So I have a few questions.
1. My Hayward heater has a set point for pool and spa set at 64 degrees. I imagine that means that if the water temp dips below that, the heater will begin to heat the water to 64. I have been warned that running the heater is expensive and I want to avoid. How low can I safely set the set point?
2. Besides reducing my filter time during winter months, is there anything else I need to do differently?
I did read about running your filter during below freezing weather I assume this is to keep water moving and prevent freezing pipes.
