How to Increase Free Chlorine in Your Pool?

If you have a swimming pool, then you know that chlorine is required in order to keep it clean. However, sometimes the amount of chlorine needed to destroy bacteria is more than what is available from natural sources. In these cases, adding free chlorine to your pool can help. Free chlorine has a much stronger disinfectant effect and is much less expensive than typical commercial pool treatments. There are several ways to increase free chlorine levels in your pool.

What is free chlorine?

Free chlorine is created when your pool chlorinates itself. However, in order to increase free chlorine levels, you will need to add it manually with a chemical pool treatment or by adding it through an automatic chlorinator. To ensure that the free chlorine is safe for you and your family, it’s best to test the levels before adding more.

Ideas that can help you increase your free chlorine levels

You can add free chlorine manually with a chlorine generator. You can also use a commercial pool treatment to help increase your free chlorine levels.

In addition, you can order aquatic plants that filter the water, which will help increase the amount of free chlorine in the water. If you have a saltwater pool, then adding a de-chlorinator is another option that can allow you to increase your free chlorine levels.

Finally, if you want to take it one step further, then you could buy an automatic pool cleaner that automatically adds more free chlorine into your pool when needed.

Costs of adding free chlorine to your pool.

The first cost of adding free chlorine to your pool is the price of the chemicals. These chemicals can range from $6.00 to $16.00 for a 100-gallon pool, depending on what type of pool you have and how often you use it.

If your pool’s pH level is higher than 7.4, then you’ll need to add muriatic acid (also known as hydrochloric acid) in order to lower the pH levels before adding free chlorine. The cost of this chemical can range from $5.00 to $14.50 per gallon, depending on the quantity and the size of your pool.


Chlorine is often used to kill bacteria and other health-threatening contaminants in a pool. However, chlorine is also the number one cause of eye, skin and hair irritation. Adding free chlorine to your pool can help reduce the levels of these contaminants and make your pool a safer place for everyone who swims in it.
