By definition, the pH-value is a measure indicating the acidity or basicity of liquids, with a value of 7 meaning that the liquid is neutral. Liquids with a pH-value less than 7 are acidic (acid), whereas liquids with a pH-value greater than 7 are alkaline (base).
The pH-value of bathing water should ideally lie between 7 and 7.2. The retention of this value is of utmost importance in view of the fact that already a pH-value of 7.5 compared to 7 requires twice the amount of oxidants in the pool water to make up for the drastically risen ineffectiveness of oxidants at higher pH-levels.
Frequent measurement and adjustment of the pH-value is also mandatory in light of pool water normally exhibiting rising scores on the pH-scale following constant chlorination and risen water temperatures in combination with the outgassing of carbon dioxide (CO2). As a matter of fact, especially hard water shows a tendency to have a higher pH-value.
Alike many other processes, this task can also be automated via the installment of the well-tried Niro-Pool pH-Pool Basic system.
