"pH-Minus"
Safely Lowers Swim Pool pH
 |
Swim Pool pHpH is a chemical measurement of acid or alkali in water. Proper swim pool pH is 7.2 - 7.6; pH over 7.6 decreases chlorine sanitizing efficiency, pH under 7.0 is acid and is corrosive to metal. If pH is too high or too low, eye, ear, nose, or skin irritation can occur. Ideal pH is 7.2 to 7.6. |
Directions
DAVIES "pH-MINUS" is added to lower swim pool pH. The exact amount of DAVIES "pH-MINUS" required will vary with water conditions. When pH is greater than 7.6, dissolve 1/2 pound (8 fl. oz.) per 10,000 gallons in a plastic bucket with warm water. Add DAVIES "pH-MINUS" solution directly to skimmer. Allow 2 to 4 hours for proper distribution, retest pH, and repeat treatment as necessary to lower the pH to 7.2.
