SpaPure Liquid pH Plus | Spa Liquid pH Increaser

SpaPure Liquid pH Plus is a fast-acting, ready-to-use liquid pH increaser that corrects low, acidic spa water. Because it's already in liquid form, there's nothing to dissolve or pre-mix — you pour it straight in and it goes right to work raising pH back into the safe range.

Low pH does real damage. When water turns acidic (below 7.2), it becomes corrosive: it eats at heater elements, pump seals, and metal fittings, degrades the spa shell over time, and stings the eyes and dries the skin of anyone who gets in. Acidic water also burns through sanitizer faster, so you spend more on chlorine or bromine while getting worse results. Since pH naturally drifts as you sanitize and use the spa, periodic correction is simply part of ownership.

Liquid pH Plus reverses that drift in minutes. Bring pH back into the 7.2–7.6 range and the water stops attacking your equipment, your sanitizer works efficiently again, and the soak feels comfortable instead of harsh — with the convenience of a simple pour.
