How to keep the heat in the pool. Trying to get an extra week or two of swimming.
What is the best way to retain / add heat to my pool. I have a blue solar cover.
Keep covered unless using pool?
Does the pool heat up more when ambient temp is above pool temp with cover on or off?
keep pump on low 24 hrs per day or run high speed part of the day?
If later which part of the day?
