The pH reading tells us whether the water is acidic or alkaline and incorrect levels may cause itchy skin and red eyes. The pH level ranges from 0 to 14, with 7.0 being neutral. Values below 7.0 are acidic.
- The Australian Standard for pool water is 7.0 to 7.8 with 7.2 to 7.6 recommended.
- Naked Pools recommends 7.2 to 7.4 for fibreglass and vinyl pools and 7.4 to 7.6 for concrete and tiled pools.
The pH level can change after heavy rain, heavy pool usage, topping up the pool, or adding chemicals, which in turn affects sanitising. Sanitiser and pH levels should be checked and adjusted frequently. Regardless of the chlorination process used, any pH drift above the recommended range (7.2 to 7.6) will inhibit the sanitising effect of your chlorine.
