Having a pool is a great way to enjoy the summer and relax, but maintaining the right pH balance can be a challenge. If the pH level in your pool is too high, it can cause skin and eye irritation, cloudy water, and reduce the effectiveness of chlorine. Lowering the pH level is essential to ensure a safe and enjoyable swimming experience. In this article, we will discuss some cheap and effective ways to lower the pH in your pool.

Testing the pH Level

Before taking any action, it is crucial to test the pH level of your pool water. You can easily purchase a pool testing kit from a local store or online. Follow the instructions to obtain an accurate reading of the pH level. The ideal pH range for a pool is between 7.2 and 7.6. If the test reveals that your pH level is higher than 7.6, it’s time to take action.

Use Muriatic Acid

Muriatic acid, also known as hydrochloric acid, is a popular and affordable option to lower pH in a pool. It is readily available at most hardware or pool supply stores. When using muriatic acid, it is essential to follow the manufacturer’s instructions and wear protective gloves and eyewear. Start by adding a small amount of acid to a bucket of water and then carefully pour it into the pool. Be sure to distribute it evenly and allow the water to circulate for at least 8 hours before retesting the pH level.

Vinegar as a Natural Alternative

If you prefer a more natural approach, vinegar can be used to lower the pH level in your pool. White vinegar, commonly found in most households, contains acetic acid, which can effectively reduce pH levels. Start by diluting the vinegar in water before adding it to the pool. Use a ratio of one cup of vinegar for every 500 gallons of water. Slowly pour the mixture into the pool, focusing on areas with high pH levels. Allow the water to circulate for a few hours before retesting.

Aeration Method

Another cost-effective way to lower pH in your pool is through the aeration method. This method involves increasing the oxygen levels in the water, which helps to lower the pH naturally. You can achieve this by running your pool’s jets or waterfalls, using a fountain or air pump, or even by attaching a hose to a return jet and letting the water spray into the pool. The increased surface area and contact with air will aid in lowering the pH level over time.

Baking Soda for Minor Adjustments

If your pH level is only slightly above the desired range, baking soda can be used as a quick and inexpensive fix. Baking soda acts as a pH buffer and helps to stabilize the water. Start by adding a small amount of baking soda to the pool, following the manufacturer’s instructions based on the size of your pool. Allow the water to circulate for a few hours before retesting. Remember to add baking soda in small increments to avoid overshooting the desired pH level.


Maintaining the right pH balance in your pool is crucial for a safe and enjoyable swimming experience. By using these cheap and effective methods, you can easily lower the pH level in your pool without breaking the bank. Remember to always test the water before making any adjustments and follow the instructions carefully. Whether you choose muriatic acid, vinegar, aeration, or baking soda, regular monitoring and maintenance will ensure that your pool remains in optimal condition all summer long.
