WATER
QUALITY
Your water BALANCE should be kept within the following levels for trouble free operation
SALT - Sodium, Mineral or Magnesium
Measurement Interval - once a month
4000 mg/L
pH
Measurement Interval - once a week
7.2 - 7.8 Controlling your pH is most important so that you have good active levels of
chlorine throughout the water, high pH above 8.0 will reduce the effectiveness of chlorine
When pH is high, Adding Hydrochloric acid will lower the pH
When pH is low, Adding Sodium bicarbonate will raise the pH
Stabiliser
Measurement Interval - Every 4 - 6 weeks
Stabiliser level should be kept between 30-70 mg/L, levels higher than this aren’t required.
Stabiliser should be measured by your pool shop every 4-6 weeks but most importantly in
summer when UV levels are highest
Chlorine
Measurement Interval - once a week
Chlorine ( Free Chlorine ) should be measured once weekly and kept between 2 - 3 mg/L for
effective disinfection, adjust the chlorinator output percentage or the pump run time to
either increase or decrease this level as required
Total Alkalinity
Measurement Interval - 4 -6 weeks
80 - 150mg/L
Calcium Hardness
Measurement Interval - every 3 months
175 - 300mg/L
8.
