SpaGuard's pH Decreaser provides spa owners with an easy way to lower high pH and alkalinity down to optimal levels, simply by adding this quick-dissolving granular formula to the water. pH Decreaser gradually lowers your pH and alkalinity until at the desired level, and also prevents scale build-up and cloudy water that also usually occurs when your spa operates at the high-end of the pH scale.
