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. Directions Use 5 g (1 level teaspoon) for every 40–80 L (10–20 US gallons) once or twice a month (or as necessary to maintain a pH of 7.0.) Neutral Regulator® may be be initially used daily in cases of high alkalinity until 7.0 is established. It may be added directly to the aquarium at any time. Ideally, it should be used when adding or changing water by dissolving in the replacement water. For precise dosing, use the Seachem Digital Spoon Scale.
