Why Saltwater Pools Tend to Have Rising pH
Saltwater pools often show rising pH because aeration and system operation can accelerate carbon dioxide loss from the water. Total alkalinity, water features, and source water also affect the trend.

What homeowners should know
Test trends, not one isolated reading.
Review total alkalinity and aeration sources.
Confirm the salt cell is producing appropriately.
Use measured adjustments and keep chemicals separate.
Why the recommendation depends on the pool
Never mix acid and chlorine or add them together. Follow product labels and obtain professional help when chemical handling is unfamiliar. The right decision depends on verified readings, equipment condition, recent weather, pool use, and the written service scope.
