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, and detoxifying 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. For further freshwater environment enhancement, use Fresh Trace™ to restore the proper level of trace elements and feed NutriDiet® Tropical Flakes for thriving, healthy freshwater community fish. Contains phosphate buffers and conditioning agents. Safe for all freshwater fish acclimated to neutral pH.
