Your water BALANCE should be kept within the following levels for trouble free operation
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 how active the chlorine is.
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 - 1-2 times per year
Stabiliser level should be kept between 20 - 50 ppm, levels higher than this aren’t
required. Stabiliser should be measured by your pool shop 1-2 times per year but most
importantly in summer when the UV levels are highest.
Chlorine
Measurement Interval - once a week
Chlorine (Free Chlorine) should be measured once weekly and kept between 2 - 3 ppm for
good disinfection, adjust the chlorinator output percentage or the pump run time to either
increase or decrease this level as required.
Total Alkalinity
Measurement Interval - once a month
80-lS0ppm
Calcium Hardness
Measurement Interval - once per year
150-250ppm
