Product Description

Spa Pure pH Up 1 lb Granular pH Increaser C002579-CS20B6

The Spa Pure pH Up C002579-CS20B6 is a granular sodium carbonate increaser that raises low pH in spa and hot tub water. Low pH makes water corrosive — it irritates bathers' eyes and skin and slowly eats away at heaters, pumps, and other sensitive equipment. This fast-dissolving dry formula brings pH back into the ideal range so everything in the spa works better and the water is comfortable again.

🚩 PRO TIP: Raise pH in small steps: add the Spa Pure pH Up C002579-CS20B6 with the water circulating, wait about 30 minutes, and retest before adding more — overshooting pH is much harder to walk back than adding a second small dose.

FREQUENTLY ASKED QUESTIONS:

  • Why is low spa pH a problem? Low pH makes spa water corrosive: it irritates eyes and skin and slowly damages the heater, pump seals, and other equipment. Raising pH into the 7.2 to 7.6 range with the Spa Pure pH Up C002579-CS20B6 protects both bathers and the spa.
  • How much Spa Pure pH Up C002579-CS20B6 do I add? When pH reads 6.8 to 7.2, add 1 oz (2 Tbsp) of Spa Pure pH Up C002579-CS20B6 per 500 gallons of spa water with the circulation running, then wait about 30 minutes and retest before adding more.
  • Does Spa Pure pH Up C002579-CS20B6 raise alkalinity too? The Spa Pure pH Up C002579-CS20B6 is a pH increaser first; sodium carbonate nudges total alkalinity up only slightly. If alkalinity itself is low, set it with an alkalinity increaser first, then fine-tune pH.
