SpaPure Liquid pH Minus | Spa Liquid pH Decreaser

SpaPure Liquid pH Minus is a ready-to-use liquid pH decreaser that instantly lowers high pH in spa and hot tub water. Because it's already in liquid form, there's nothing to dissolve or pre-mix — you pour it straight in and it goes to work, also bringing down total alkalinity along with pH.

High pH causes problems that build up quietly. When pH climbs above the ideal range, the water turns cloudy, scale starts forming on surfaces and inside your plumbing and heater, and your sanitizer loses efficiency. Since spa pH naturally drifts upward over time, a pH decreaser is a must-have — and the liquid format makes it the easiest possible way to make that correction.

Bring pH back into the ideal range and the water clears, scale stops forming, your equipment is protected, and the soak feels comfortable again.
