How do I lower the pH of my pool?

Lowering the pH of your pool is important to maintain a safe and comfortable swimming environment. A pH level that is too high can lead to problems like cloudy water, scaling, and ineffective chlorine disinfection. See our water testing products in our shop. Here are steps to lower the pH of your pool:

1. Test the Current pH Level: Use a pool water testing kit or test strips to determine the current pH level of your pool. The ideal pH range for a swimming pool is typically between 7.2 and 7.6.

2. Calculate the Amount of pH Reducer Needed: To lower the pH, you'll need to add a pH reducer or pH decreaser, which is an acid, such as our pHminus. The amount of acid needed depends on the pool's size and the current pH level. Refer to the product's instructions for dosage recommendations or consult a pool professional for guidance.

3. Safety First: Before handling any pool chemicals, ensure you are wearing appropriate safety gear, including gloves and safety goggles. Work in a well-ventilated area, and keep children and pets away from the pool during this process.

4. Dilute the Acid (if necessary): If the pH reducer you're using is very concentrated, it's a good idea to dilute it with water in a bucket before adding it to the pool. This helps prevent localized chemical reactions in the pool water. Always add acid to water - never add water to acid, it might explode: Do what you oughta, add acid to water!

5. Add the pH Reducer: Carefully pour the diluted or undiluted pH reducer into the pool water. It's best to add it in different areas of the pool while the circulation system is running to ensure even distribution. Follow the manufacturer's instructions for the correct dosage.

6. Wait and Re-Test: Allow the pool water to circulate for several hours or overnight. Afterward, retest the pH level to ensure it has reached your desired range. If the pH is still too high, repeat the process with a smaller dose of pH reducer to avoid over-acidifying the water.

7. Monitor and Adjust: Keep an eye on your pool's pH level regularly, especially during high swimmer activity or after heavy rain, as these can affect pH. Adjust the pH as needed to maintain it within the recommended range.

8. Balance Other Pool Parameters: Remember that pH is just one aspect of pool water chemistry. It's essential to also monitor and maintain proper levels of chlorine, alkalinity, and calcium hardness to ensure balanced water chemistry.

9. Consider Baking Soda (Sodium Bicarbonate): If the pool's total alkalinity is also high, which often coincides with high pH levels, you can consider adding sodium bicarbonate (baking soda) to help stabilize the pH. Baking soda can increase alkalinity without significantly affecting pH.

Always follow our instructions on the pool chemicals, and if you're unsure about any step or need additional assistance, don't hesitate to contact us for advice. Proper pool water maintenance is essential for the safety and enjoyment of swimmers.
