Neutral Regulator adjust pH to neutral (pH 7.0) from either a low of high pH and maintains it there. It softens water by precipitating calcium and magnesium while removing any chlorine, chloramine or ammonia. The use of Neutral Regulator makes other conditioning unnecessary. To lower pH below 7.0 use Neutral Regulator with Acid Regulator. To raise pH above 7.0 use with Alkaline Regulator.
