An economical way to decrease the pH of the water in your inground or aboveground swimming pool safely & effectively.

Regular maintenance of your pool's water chemistry is essential for swimmer comfort, equipment life, and effectiveness of your chlorine or sanitizer. High pH is problem found with Liquid chlorine and Cal-Hypo chlorinators. Decrease the pH properly with Pool-Trol pH Minus.

High pH leads to scaling of equipment, pool surfaces, a dramatic slowing of the chlorine's effectiveness causing quick algae growth. High pH can even cause cloudy water! Just a small difference in the pH from normal (7.4 - 7.6) to high (over 7.8) can lead to these problems.

Easy application. Just broadcast into the water.

Be sure to retest the pH after about 6 hours. Maintain the pH between 7.4 - 7.6. Always maintain good water balance.

Use Pool Care pH Minus as needed.

Use with ALL Chlorine, Salt/chlorine, bromine, Ionizers (Nature2 or Pool Frog) or biguanide (Soft Swim or Baquacil) pool care systems.
