Maintaining Pool Water Balance: pH Levels and Adjustments for Above Ground Pools

The ideal pH for a swimming pool is between 7.2 and 7.8, so if your pool's pH is 7.8 or lower, you don't need to add any pH increaser. If your pool's pH is above 7.8, you'll need to add a pH decreaser.

The amount of pH decreaser you need to add will depend on the size of your pool and the current pH level. You can use a pool water test kit to determine the current pH level of your pool. Once you know the current pH level, you can use the chart below to determine how much pH decreaser you need to add.

pH Decreaser Dosage Chart

| Current pH Level | pH Decreaser to Add (ounces per 10,000 gallons) |

|---|---|

| 7.9 | 1.5 |

| 8.0 | 3.0 |

| 8.1 | 4.5 |

| 8.2 | 6.0 |

| 8.3 | 7.5 |

| 8.4 | 9.0 |

For example, if your pool's pH is 8.0, you would need to add 3 ounces of pH decreaser per 10,000 gallons of pool water.

Be sure to follow the directions on the pH decreaser package carefully. It is important to add the pH decreaser slowly and stir the pool water thoroughly to ensure that the pH level is evenly distributed.
