Some consider this the most important component of water balance. It measures how acidic or basic your water is. If it is not kept in check you run the risk of damaging your equipment, i.e. heating elements, pump seals, and the internal works on gas fired heaters. Listed are the most common problems associated with both high or low pH levels:
High pH Readings
Low pH Readings
|Poor Sanitizer Efficiency||Poor Sanitizer Efficiency|
|Cloudy Water||Corroded Metals/Equipment|
|Scale Formation||Skin and Eye Irritation|
|Shorter Filter Runs||Etched or Stained Plaster|
|Skin and Eye Irritations||Destruction of Total Alkalinity|
The ideal pH range for spas is 7.2 to 7.8. Any reading below 7.2 means your water is acidic. To correct this you would add Spa Up. If the pH reading is above 7.8, it means the water is basic or alkaline. To bring the pH level down you would use Spa Down. Another pH balancing product is called pH Balance it works great following some simple instructions included. Once again to achieve these readings, you will need a test kit or test strips. It is also best to get your sanitizer level at a reasonable measure before testing the pH.
IMPORTANT NOTE: Before adding any chemicals to adjust your pH levels, the total alkalinity must be balanced first.
