Clorine in swimming pool water is effective when the PH is kept between 7.2 and 7.6 if the PH is below 7.2 the water is too acidic and must be raised by addition of a low PH adjuster (PH Plus).
PH plus is available in powder form thus it is best premixed before addition to swimming pool.
How to Use pH Plus to treat swimming pool water
Dosage should be effective by adding 50gms PH plus per 10m³ of pool water for each 0.1 increase of the PH required.
The pump should run for about 4 hours before the PH is checked and adjusted accordingly.
Suggested dosage for a 10m³ sample pool
Water pH | 7.0 | 6.8 | 6.6 | 6.4 |
pH Gms | 200 | 300 | 400 | 500 |
