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.
