Hot Tub Things pH & Alkalinity Up – 2 lb Granular Water Balancer

Contains high-quality sodium bicarbonate designed to increase both pH and total alkalinity simultaneously in spa water, reducing pH bounce and improving chemical stability.

Raises total alkalinity to the preferred range of 80–150 ppm and lifts pH to 7.2–7.8, protecting equipment from corrosion and preventing surface etching.

Enhances sanitizer effectiveness—balanced water ensures chlorine or bromine work properly, avoiding cloudy water and reducing odor and eye irritation.

Ideal for all spa and hot tub types (chlorine, bromine, salt, mineral, and ozone systems), use after chemical shock or spa refills.

Packaged in a convenient 2 lb resealable jar—enough for multiple treatments and easy to store.
