How to Maintain Swimming Pool Water Chemistry

Whether it’s inground or above-ground, a lap pool or a giant swimming pool, it’s crucial to maintain good pool water chemistry to keep your investment maintained.

If you’re not familiar with how chemistry works for your pool water, there are a few basic principles you need to know.

Read on for some helpful tips about pool water chemistry that will make maintenance easy.

Understand pH, Alkalinity, and Calcium Levels

The pH level in your pool water needs to be balanced to avoid becoming too acidic. Ideally, the pH level of the water should be somewhere between 7.4 and 7.6. You can easily test your water with a kit and use a pH increase when needed.

Another crucial part of pool water chemistry is the alkaline levels. These levels should be between 100 to 150 ppm, and alkaline serves as a pH buffer to keep the levels in check. Alkalinity increaser can also help you maintain the proper levels in your pool.

Finally, calcium hardness is important since it can mess up your plaster or lining if levels are too high. The calcium hardness should be between 170 and 300 ppm, and you may add calcium hardness to protect your walls and equipment.

Balancing Levels Through Pool Water Chemistry

To protect your pool and your skin, you should test your pH and alkalinity levels once a week with a home test kit or testing strips. Always keep a pH increaser, pH reducer, and alkalinity increaser on-hand to ensure that your pool water levels stay balanced. 

The alkalinity increaser should increase both alkaline and pH levels as needed, while the pH decreaser will lower both pH and alkalinity. You may have to try a few different measurements and combinations until you find the perfect amount for your water.

As long as your pool water is balanced at all times, the chlorine will work more effectively. It also helps to protect the pool itself from excess wear and tear as well as scaling and other damage.

Sanitizing Your Pool

In order to keep your pool safe and clean, you need to add specific chemicals to the water. Chlorine is the most commonly used, but you can also use salt, stabilized chlorine, and other minerals depending on how your pool is set up.

Ideal chlorine levels should be between one to 3 ppm. This chemical is extremely effective at killing algae and bacteria, and it’s also very affordable. 

To add chlorine to your pool water, you can use chlorine tablets, powder, granules, or a salt-chlorine generator. This process takes regular table salt and turns it into chlorine, making the water softer and “less harsh” on the eyes, hair, and skin.

Using Chemistry to Keep Your Pool Clean

When you know the basics of pool water chemistry, it’s easy to ensure that your water and pool are protected. Use a test kit or strips to check water weekly and add the specific chemicals as needed.
