Pool Water Chemistry Explained

You don’t have to be a water chemistry professional to understand the science behind how chemicals keep your pool water safe. Adding the appropriate chemicals to your pool is vital because it helps the filters keep your pool clean and safe for swimming. By carefully manipulating the pool water chemistry in your pool, you can keep dangerous bacteria from thriving and making your family sick during a routine summer swim.

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, the chlorine kills any bacteria that might be lurking in the water. You can add chlorine to your pool using a chemical feeder right after the filtering process. 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.

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

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 on your metal ladder and even lead to skin irritation for swimmers. On the other hand, water that is too alkaline can become cloudy and lead to scaling on the surface of the pool.

Regularly test the pH level of your pool water and you can easily see whether your chlorine is doing the job or if you need to adjust the amount you add.Target water readings for swimming pool water chemistry
