Maintaining a clean pool is important. You want to make the most of your pool and be able to enjoy it whenever you want. Keeping a clean pool is so much more than just removing debris. The sanitizers used in pools are an important factor that every pool owner should understand.

Whether you are a new pool owner or you just want to know more about properly maintaining your pool, it is important that you understand pool chemicals, the different kinds, and how to measure them. Many pools use chlorine, but there are other chemical options you can use.

We will be able to help your pool maintain a healthy level of chemicals, no matter which type of chemicals you choose to use! We wanted to help pool owners better understand the sanitizers that are being put in their pools. In this blog, we are going to talk about the different types of chemicals that you can use in your pool!


Chlorine is the most common pool chemical used. It kills harmful microorganisms that can cause health-related problems. Chlorine is the most widely used pool sanitizer, which makes it a great choice if you are unsure of what to use. This pool sanitizer is powerful and effective and comes in a variety of options. You can find chlorine in the following forms:

  • Liquid
  • Granular
  • Tablets

Chlorine tablets are the best option for providing your pool with a constant supply of chlorine. If you need to give your pool a shock treatment, the liquid or granular forms of chlorine are the best options. Chlorine can also be generated through a chlorine generator or Salt System.

Outdoor pools often need stabilized chlorine, which contains cyanuric acid. This stabilizer helps to keep the chlorine from breaking down in UV light and is found in stabilized chlorine tablets and some granular forms. While this is the most common sanitizer for pools, some people may find it too harsh for their skin.


Bromine is another pool chemical that has become a popular choice. This chemical is very similar to chlorine, however, it is a gentler sanitizer. This makes it a great option for those who find chlorine too harsh or have allergic reactions to chlorine.

Bromine is available in both tablets and granular form. It is extremely sensitive to UV light, which means that it dissipates quickly. If your pool is exposed to a lot of sun, you will want to make sure you are constantly replenishing the chemicals. Since bromine needs to be replenished regularly when your pool is exposed to the sun, a pressurized feeder, called a brominator, can help supply your pool with bromine at all times.

Bromine is more effective when it comes to killing algae and is just as effective at killing bacteria as chlorine, which makes it a great alternative, especially if someone in your family is negatively affected by chlorine.


Polyhexamethylene Biguanide, or PHMB, is another sanitizer that is completely chlorine and bromine-free. This sanitizer is often sold in stores under the name Baquacil. PHMB is effective when it comes to killing bacteria and algae in your pool. This is considered one of the most swimmer-friendly sanitizers, making it a great option for families with sensitive skin.

This type of sanitizer remains in your pool longer than others, which makes it an easier choice to maintain. However, PHMB does not oxidize your water, which means that you will have to use hydrogen peroxide weekly. This sanitizer type is also incompatible with other pool chemicals, including chlorine and bromine.


Ionization or a natural mineral sanitizer uses silver and copper ions to sanitize your pool. This is a natural alternative to the traditional choices in pool chemicals. The release of silver and copper kills bacteria, viruses, and helps prevent algae. With this sanitizer, you may need a weekly chlorine shock treatment to help keep your pool properly maintained.

However, high levels of copper are what leads to green hair and can leave a brown or black stain on the pool’s surface. Even though this sanitizer greatly reduces your need for chlorine, frequent testing is recommended to ensure proper levels. This can ensure that the level of copper is monitored and maintained.

These are some of the main sanitizer options for your pool. In future blogs, we will also discuss water balancers, algaecides, and oxidizers to ensure your pool has all the chemicals it needs to stay clean and properly maintained. Contact Spic N Span Pools to start your pool services now!
