Spa Water Treatment
Recommended Chemical Values
Chlorine......................... 1.5 - 3.0 PPM ( Parts Per Million )
pH.................................. 7.4 - 7.6
Total alkalinity ................100 - 120 PPM
It is important to maintain your spa water chemistry to the above values to ensure a healthy experience
both for you as bathers and for your spa pool equipment.
PH
This is a measure of how acid or alkaline the spa water is (below 7.0 is acid, above 7.0 is alkaline). Low pH will
cause corrosion of any metalwork in the water (element, thermostat pockets). High pH will cause scale formation
and cloudy water.
Total Alkalinity
This is a measure of how resistant your spa water is to change of pH. A low TA (0 - 80 ppm) will allow the pH to
uctuate rapidly normally to the acid end and will make it very hard to correct the pH back to the ideal range.
Chlorine
Levels of sanitiser are important to prevent the build up of bacteria, and algae in the pool water. Chlorine is not the
only sanitiser available to do this. Other sanitisers are Bromine, Ozone.
Damage to the element, thermostat pockets and associated metalwork due to the poor maintenance of water
chemistry is not covered by warranty.
