To raise pH we recommend using Easy pH or if not available - Soda Ash (sodium carbonate). This will raise the pH more than the Total Alkalinity. You will need to perform a Base Demand test to accurately determine how much pH increaser you need.
We recommend you keep your pH between 7.8 and 8.2 for maintenance according to our Hamilton Index.
This table will give you a rough estimate for dosing:
pH change
| Easy pH per 10,000 gallons
| Soda Ash per 10,000 gallons
|
+.2
| 3 ounces
| 6 ounces
|
+.4
| 5 ounces
| 12 ounces

| 7 ounces
| 1 pound 2 ounces*
|
+.8
| 9 ounces
| 1 pound 8 ounces*
|
+ 1.0
| 11 ounces
| 1 pound 14 ounces*

*In general, it is not recommended to add more than one pound of pH increaser per 10,000 gallons at one time to a pool. This may lead to staining.
