AquaSPArkle Spa PH Minus 1.5kg


Test the pH of your spa water and if it is above 7.6, use AquaSPArkle Spa pH Minus to lower it.

Spa pH Minus can also be used for lowering Total Alkalinity if it rises above 150mg/l (ppm). 

  • Granular pH reducer
  • Can also be used for reducing total alkalinity
  • Ideal pH range is 7.2 to 7.6.
Maintaining the correct pH balance is important for a number of key reasons.  The correct pH level ensures that your santisers work effeciently keeping your Spa clean and safe.  An incorrect pH balance can cause bather discomfort such as stinging eyes, and can damage your Spa equipment such as pumps and heaters.
