When it comes to keeping your pool clean and clear, chlorine is the most commonly used chemical. However, some pool owners may wonder if they can use bleach instead of chlorine to sanitize their pool. In this article, we will explore whether bleach is a suitable alternative to chlorine in pool maintenance.

What is Chlorine and Bleach?

Chlorine is a chemical element that is commonly used in swimming pools to kill bacteria and other harmful microorganisms. It comes in various forms, including tablets, granules, and liquid. On the other hand, bleach is a solution of sodium hypochlorite, which is a type of chlorine compound. It is often used as a household cleaner and disinfectant.

Can You Use Bleach in a Pool?

Yes, you can use bleach in a pool as a substitute for chlorine. However, it is important to note that bleach has a lower concentration of chlorine than most pool chlorine products. As a result, you will need to use a higher amount of bleach to achieve the same level of sanitation as chlorine. This can make it a more expensive option in the long run.

Benefits of Using Bleach

One of the main benefits of using bleach in a pool is that it is readily available and can be purchased at most grocery stores. It is also easy to use, as you simply pour it into the pool water. Additionally, bleach is less harsh on pool equipment and surfaces than some other chlorine products.

Drawbacks of Using Bleach

While bleach can be a suitable alternative to chlorine in a pool, it does have some drawbacks. As previously mentioned, you will need to use a higher amount of bleach to achieve the same level of sanitation as chlorine. This can make it more expensive in the long run. Additionally, bleach can cause cloudiness in pool water if not used properly.

Tips for Using Bleach in a Pool

If you decide to use bleach in your pool, there are some tips to keep in mind. First, make sure to use unscented bleach, as scented varieties can contain additional chemicals that can harm your pool. Additionally, you should only use bleach in a well-ventilated area and avoid inhaling the fumes. Finally, be sure to use the proper amount of bleach based on the size of your pool.


In summary, bleach can be used as a substitute for chlorine in a pool. While it has some benefits, such as being readily available and easy to use, it also has drawbacks, such as being more expensive in the long run. Ultimately, the decision to use bleach or chlorine in a pool will depend on personal preference and budget. Regardless of which option you choose, it is important to properly maintain your pool to keep it clean and safe for swimming.
