You don’t have to be a water chemistry professional to understand that chemicals keep your pool water clear and healthy. Adding the appropriate chemicals to your pool is vital because they keep the pool water balanced and sanitized while also improving water quality, stopping corrosion and scaling of equipment, and preventing algae growth. By carefully managing the chemical balance in your pool, you protect your pool and your swimmers. Read on to learn more about basic pool water chemistry and how to keep your pool water in the best shape possible. 


To eliminate unwanted pathogens and bacteria, the first step is to add a disinfecting agent to the water. The most common way to handle this is with chlorine as a solid in calcium hypochlorite or a liquid in sodium hypochlorite. When you add these compounds to your pool, chlorine kills any bacteria that might be lurking in the water. 

You can add chlorine to your pool using a chemical feeder right after filtering. If you don’t use a chemical feeder, you can add it directly to the pool by placing chlorine tablets in skimmer boxes. However, this method is generally not as safe because it makes the chlorine levels much more concentrated in the area around the box. This can be harmful to your swimmers as well as your pool’s interior and equipment.

Most standard pool chlorines are created with a stabilizing agent like cyanuric acid. This helps to prevent any reaction from exposure to sunlight and it keeps the chlorine from degrading as quickly.

Know Your pH Levels

Another important element of pool chemistry is the pH level. You can use simple strips to test the water’s pH levels and decide whether you need to adjust the amount of chlorine. If the water is too acidic, it can cause corrosion of your pool’s interior and equipment and it can also lead to skin irritation for swimmers. On the other hand, water that has high alkalinity levels can become cloudy and lead to scaling on the surface of the pool.

Regularly testing the pH level of your pool water allows you to easily see whether your chlorine is doing the job or if you need to adjust the amount you add.

A Few Things to Remember

1. Improperly stored or mixed pool chemicals can pose significant health and safety hazards.

2. Rain, dirt, debris, and even your bather load can also alter your pool’s water chemistry. Be sure to clean your pool and test your water chemistry after significant rainfall or after a pool party. 

3. Extreme heat and long periods of strong sunlight can reduce chlorine’s effects in your pool water and cause evaporation. It is important to pay close attention to your pool’s water chemistry when experiencing heat waves.
