High pH
Why does pool pH rise?
- Heat and intense sun: promote a rise in pH in the middle of summer.
- Intensive use: many swimmers alter the balance of the water.
- Hard filling water or with high alkalinity.
- Some disinfection treatments tend to raise the pH.
- High Total Alkalinity: if it exceeds 150 ppm, it pushes the pH up.
