Neutral Regulatorï¿½ 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 Regulatorï¿½ makes other conditioning unnecessary. To lower pH below 7.0 use Neutral Regulatorï¿½ with Acid Regulatorï¿½ (or Discus Bufferï¿½). To raise pH above 7.0 use with Alkaline Regulatorï¿½. 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.
