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.
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 fluctuate rapidly normally to the acid end and will make it very hard to correct the
pH back to the ideal range.
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.
t 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.
Damage to the element, thermostat pockets and associated metalwork due to the poor
maintenance of water chemistry is not covered by warranty.
