4.2 I Balancing the water

The water used must originate from a supply network compliant with Directive 98/83/EC on the quality of water intended
for human consumption. In order for the water to be treated optimally, carry out measurements and adjust the values
in accordance with the following recommendations:
4.2.1 Seasonal analyses in "preparation for re-use"
- Stabiliser (cyanuric acid) (<30 mg/L, ppm): the stabiliser protects chlorine from the destructive power of the sun's
U.V. rays. Excessive stabiliser can block the disinfecting power of chlorine and turn the water turbid.
±
- Metals (Cu, Fe, Mn) (
can cause permanent stains.
4.2.2 Monthly analyses
- TH (10-30°f) or (100 - 300 mg/L CaCO
carbonate), and this value can vary significantly depending on the geographical region concerned.
- TA (8-15°f) or (80 -150 mg/L CaCO
stabilised. It is important that the TA is adjusted before the pH.
4.2.3 Weekly analyses
- pH (7.0 - 7.4): the pH measures the acidity or alkalinity of the water. A pH in the range 7.0 to 7.4 helps to preserve
the pool equipment and maintain effective disinfection. Taylor's balance method, as shown below, is used to
adjust the pH value:
Taylor's balance
- Free chlorine (0.5 - 2 mg/L or ppm): this quantity of free chlorine makes the water both disinfected and disinfecting.
Contact your retailer to determine the type of corrector product or automatic control appliance to
be used to adjust the values.
0 mg/L, ppm): metals damage the metallic parts of the pool (corrosion phenomenon) or
, ppm): the TH measures the calcium hardness (quantity of calcium
3
, ppm): the TA measures the water alkalinity, and this value allows the pH to be

: Mark the value of the TA after
adjustment.
: Draw a line between the TH value
and the TA value to determine the pH
value to be adjusted.
