Dual pH Buffer System – Total Alkalinity

Alkalinity in small bodies of water (such as spas) increases/decreases faster compared to larger bodies of water.

Aeration created by spa jets increases pH

  • More pH buffer will be used compared to similar volumes of water
  • Greater effect on alkalinity

Recommendation:  Dual pH buffer system will allow the operator to manage the TA situation more affectively.

  • Acid system ≈ $2,000-$2,500
  • CO2 system ≈ $3,000-$4,000
  • Dual system (Manual) - $5,150-$6,650
  • Dual System (Auto) - $6,500-$8,500
