The nights start getting a little cooler (40 degrees or less), and pool owners recognize it as the first sign that the season is preparing to change.

When its time to get ready to close up your pool, taking the time to do it right will prevent problems during the winter and help avoid delays opening the pool when the warm weather returns. About three days to a week before you will close your pool, begin preparing it. Adjust the water chemical balance to the following ranges:
pH: 7.2-7.6
Alkalinity: 80-120ppm
Calcium Hardness: 180-220ppm
Reduce filtering times gradually over a week
