Seachem 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 Seachem Neutral Regulator makes other conditioning unnecessary.Contains phosphate buffers and conditioning agents. Safe for all freshwater fish acclimated to neutral pH.Application and dosage Seachem Neutral RegulatorUse 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.) Seachem 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 (accessorie).
