Understanding pH level in spa water

What is pH level?

Some believe pH is this the most important component of water balance. pH is the measurement of how acidic or basic your water is.

If the pH of your spa water is not kept at the appropriate level there is a greater risk of damage to the spa equipment. This includes your spa heater element, spa pump seals, as well as other internal surfaces.

Listed below are a number of issues caused by a pH level that is too high or too low:

High pH reading: Above 7.8 pH

Poor efficiency of sanitiser
Cloudy spa water
Scale formation on spa surfaces
Reduced Spa Filter Life
Skin and eye irritation including rash

Low pH readings: Below 7.2 pH

Poor efficiency of sanitiser
Corrosion develops on metal equipment
Skin and eye irritation including rash
Stained plaster (Concrete spa or pool)
Severe reduction of Total Alkalinity

Readings of 7.2 - 7.8 pH are ideal for spas.
If your reading is below 7.2 pH then your water is acidic and you need to add a pH increaser or alkalinity increaser which will raise the pH and Total Alkalinity.
If your spa water pH reading is above 7.8 pH then it is alkaline and needs a pH Decrease.
