Seachem Liquid Neutral Regulator 250ml

Liquid 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 Liquid Neutral Regulator' makes other conditioning unnecessary. To lower pH below 7.0 use Liquid 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.

Directions
Use 1 capful (5 mL) for every 10 L (2.5 US gallons) once or twice a month (or as necessary to maintain a pH of 7.0). Liquid Neutral Regulator' may be added directly to the aquarium at any time. Very hard water may require a double or triple dose.
Contains phosphate buffers and conditioning agents. Safe for all freshwater fish acclimated to neutral pH.

FAQ
After 1 week of continued use, the pH is still running basic - 7.4. The water turns cloudy when it is added.
A: From the information you provided about cloudy water I am assuming that you have very hard water. It is completely normal for the water to cloud as Neutral Regulator' is trying to soften the water. Neutral Regulator' is designed to work for the general water municipalities. In unusually high KH conditions it may be necessary to add more (directions state to add as necessary) Neutral Regulator' to combat the KH buffering system that is most likely found in your water. It is a competition between the two buffers, Neutral Regulator' is trying to bring your pH down and the high KH (that is most likely found in your water) is trying to bring pH up. This is a situation that does not occur often. You may have to add a stronger dose (at one time, Neutral Regulator' is non toxic) to bring pH down or in the rare situation you may need to use Acid Buffer to bring down your hardness.
