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. Contains phosphate buffers and conditioning agents. Safe for all freshwater fish acclimated to neutral pH.
