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. Use Fresh Trace# to restore the proper level of trace elements required by thriving, healthy freshwater community fish.
