pH LEVEL IN THE SWIMMING POOL:
The pH level must be maintained within the recommended range.
It is very important to control this parameter twice per week or more, depending on exposure to the
sun and the number of bathers in the pool.
a) Avoid that the water is corrosive (low pH < 6.8 / 7.2 depending on the type of swimming pool)
or that it has a tendency to calcify (high pH, >7.8).
This may deteriorate the installation
of the swimming pool.
b) Correct pH value (lower than pH 7.5) will help to improve the lifetime of the electrode
since the formation of calcium will be minimised.
c) A high pH value has a low HCIO % (Hypochlorous) and a high CIO % (hypochlorite).
HCIO is actually the oxidant-disinfectant agent in the swimming pool; which explains that a pH of
6.8, 7.2 is the most reasonable and recommended depending on the type of swimming pool.
In general, when electrolysis system is used to control pH, an agent must be applied (solid-
liquid) pH-minus. Products based on diluted sulphur are recommended. Avoid hydrochloric
acid (HCI) since this produces a corrosive atmosphere in the place where it is found, even
though it is covered. The use of automatic pH regulators (pumps-instrument) is recommended.
Depending on the pH, the chlorine produced will act differently.
At the recommended pH a higher % of hypochlorous than hypochlorite.
Hypochlorous is much more oxidant-disinfectant (HClO).
