To raise the pH level in a pool, the most common and effective method is to add a chemical pH increaser, which is typically sodium carbonate (also known as soda ash or washing soda). Another option is to use baking soda (sodium bicarbonate), but this primarily raises alkalinity along with pH, while soda ash raises pH more directly and significantly. Here is how to raise pH in a pool:
- Test your pool water to understand the current pH level.
- If pH is below the ideal range (7.4 to 7.6), add soda ash (sodium carbonate) for a direct pH increase.
- If both pH and alkalinity are low, use baking soda (sodium bicarbonate) to raise both.
- Add the chemical while the pool pump and filter are running to circulate the water.
- Sprinkle the powder evenly across the pool surface (broadcasting).
- Wait about 20 minutes to let the chemical dissolve and distribute, then retest pH.
- Repeat dosing if necessary, but add chemicals gradually to avoid overshooting.
Aerating the water (e.g., using waterfalls or pool features) can also raise pH without affecting alkalinity. Raising the pH helps prevent corrosion of pool surfaces and equipment, improves chlorine effectiveness, and prevents eye and skin irritation. In summary, use soda ash for a more pronounced pH increase, and baking soda if alkalinity also needs to be raised. Add chemicals carefully and retest for precise balance.
