Dolphin pH minus
You use pH Minus to keep your bathing water in balance. It is important that you measure the pH value at regular intervals - preferably at least once a week.
If the water has a pH value above 7.4, we recommend that you use pH Minus Granules, powder, to lower the pH value because a high pH value results in poorer chlorine disinfection, skin irritation, lime precipitation and turbidity.
Instructions for use pH Minus
Carefully sprinkle the amount of granules to be added to the bath water while the circulation pump is on.
Repeat the treatment if necessary by adding another dose of pH Minus until the pH value is between 7.0 and 7.4.
You should therefore pay close attention to the dosage and also regularly check and adjust the chlorine, pH and alkali levels to the recommended values:
Chlorine 1,0-1,5 mg/l;
Alkalinity 80-120 mg/l.
The basis of good bathing water is the mechanical purification of the water. Make sure to clean the pool often and backwash the filter once a week (more often if necessary).
It is preferable to lower the PH value in batches in order to reach the optimum PH value. After calculating how much agent should be added, add half and then wait 30-45 minutes and take another measurement. Depending on the results of the water test, the remaining Ph is then added.
