Spa Pure pH Down 24 oz Granular pH Decreaser C002625-CS20B8

The Spa Pure pH Down C002625-CS20B8 is a granular dry acid that lowers high pH in spa and hot tub water quickly and safely. The sodium bisulfate formula starts working the moment it hits the water, with no waiting period before you soak — and bringing high pH back into range prevents the scale buildup, cloudy water, and wasted sanitizer that alkaline water causes.

🚩 PRO TIP: Add Spa Pure pH Down C002625-CS20B8 in measured doses with the circulation running, then wait at least 30 minutes before adding a different balancer — stacking pH and alkalinity products back to back makes your test readings hard to trust.
