proper pH range in winter for pool not closed

[engrav]

Hi
Do not close in winter out here so...
Do I keep on with the same pH range?
Searched but did not see the answer for pools not closed.
Thanks.

Normal pH range anywhere in the 7's. Keep an eye on your CSI as your water gets colder and use pH adjustment to keep CSI between +0.3 to -0.3
