BioGuard Spa Aquality slowly lowers pH and decreases Total Alkalinity to help prevent scale build-up, cloudy water and eye irritation.

  • High pH and TA may cause skin and eye irritation and reduce chlorine/ bromine efficiency.  
  • High pH and TA can cause scale to form on surfaces and equipment, resulting in poor filtration, circulation and equipment failure. 
  • pH should be maintained between 7.4-7.6 and TA between 80-150ppm depending on the surface, for best sanitiser performance and water quality and bather comfort. 

Product Features:

  • 1000g/kg sodium hydrogen sulphate.
  • Decreases Total Alkalinity.
  • For all spa surfaces.
  • Classified as Non-Dangerous Good

Product Benefits:

  • Helps improve chlorine/bromine efficiency.
  • Prevents corrosion of equipment.
  • Reduces the risk of scale formation. 
  • Safer to use than liquid acid (hydrochloric acid, muriatic acid).
