Neutral Regulator� adjusts pH to neutral (pH 7.0) from either a low or 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� (or Discus Buffer�). To raise pH above 7.0 use with Alkaline Regulator�. All of these products will enhance and stabilize the freshwater aquarium environment.
