The most commonly used and efficient product to lower alkalinity is Ph down.  pH Down, known as dry acid, will lower your pH.  The recommended pH for pool water is within the range of 7.2 or 7.6 or slightly on the alkaline side, preferably about 7.2  If the pH gets higher than 7.8, the water is becoming too alkaline.  When water is too alkaline, it reduces the effectiveness of chlorine – the pool chemical that kills pathogens.  Water with a pH that is too high can also cause skin rashes, cloudy water and scaling on pool equipment.

You can reduce the total alkalinity in your pool with a strong acid, such as muriatic acid or sodium bisulfate (pH decreaser).  You need to pay attention to the directions on the bottle, mixing only what you need to bring your alkalinity levels back to the ideal range of 100 to 150 ppm
