Specially formulated to decrease the pH of the pool water.
REGULATORS : pH- Minus is a granular powder that does not cause turbidity. It works effectively with too high pH values and allows to reach quickly the ideal pH value.


pH is the measure of how acid/alkaline the pool water is. If pH is too low, the water can be corrosive to pool equipment. If pH is too high, then the chlorine becomes much less effective for sanitization.

When it comes to pool care, sodium bisulfate (pH=1) is an acidity regulator (ph decreaser) that is used to lower the pH and total alkalinity of your pool water.

In the Swim Granular Pool pH Reducer is easy-to-use and dissolves fast. Maintaining proper pH and alkalinity balance is key to a pool’s health. pH balance is how acidic or basic the water is. The pH scale is 0-14, and pools & spas should range between 7.2 – 7.6 with an ideal level of 7.4. Alkalinity helps to stabilize the pH balance in your pool. Alkalinity range for pools and spas should be between 80 – 120 ppm. If the pH and alkalinity balance fluctuate high or low, you may experience negative side effects.
