Description
Lowers pH and Total Alkalinity for Clear, Comfortable Water
Sirona™ Spa Care Spa Down is a granular balancer that lowers both pH and total alkalinity in spa and hot tub water. Keeping them in range helps sanitizers work, protects equipment and keeps water sparkling.
High pH reduces sanitizer efficiency and can cause cloudy water or scale. A small dose of Spa Down brings it back.
Prevent Scale and Cloudy Water
High pH and alkalinity encourage scale and cloudiness. Spa Down lowers both to help prevent scale, cloudiness and discolored water.
Clear water starts with balance.
Help Your Sanitizer Work Better
Sanitizers lose efficiency when pH runs high. Lowering pH to the 7.2 to 7.8 range helps them work as intended.
That also improves bather comfort.
Small, Simple Doses
Add just ¼ oz (1½ tsp) per 500 gallons with circulation running, then retest after 3 hours.
Repeat if needed until water is balanced.
