When your spa’s pH climbs too high, your sanitizer starts losing its effectiveness — even if the chlorine or bromine levels look fine on the test strip. High pH can also lead to cloudy water and scale buildup on surfaces. SpaGuard pH Decreaser brings pH back down into the ideal 7.4–7.8 range quickly, helping your sanitizer work the way it’s supposed to and keeping your water comfortable and clear.

•   Lowers pH to the recommended range of 7.4–7.8
•   Restores sanitizer effectiveness reduced by high pH
•   Helps prevent cloudy water and scale formation

•   Easy to dose — add gradually and retest after 30 minutes
