Swimming Pool Chemicals: A Primer

Swimming Pool Chemicals: A Primer

Pool chemicals are an integral part of maintaining your pool environment. They ensure the water remains safe and healthy for you, your family members, and guests to enjoy.

Your swimming pool’s water chemistry is determined by levels of chlorine, bromine, pH balancers and algaecides. All these chemicals work together to keep your pool clean and healthy for you and your family to enjoy.


Chlorine is a chemical commonly used in swimming pools to keep the water clear and safe for swimmers. It acts as a disinfectant, capable of eliminating bacteria, protozoans and other organisms. You can learn more about health and safety by clicking the link.

Chlorine is necessary to keep pool water clear and healthy, but it may have adverse effects on people. Chlorine may cause itching skin or red eyes, among other things.

Chlorine gas can be highly toxic when concentrated, leading to respiratory issues like coughing, chest pain and water retention in the lungs.

The amount of chlorine absorbed into the body depends on exposure time and frequency. It’s essential to remember that chlorine absorbs much less concentration when exposed to other chemicals like oxygen or nitrogen than pure chlorine does.


Borate is an essential pool chemical that works to maintain the pH level of your water, helping prevent algae growth and keeping your swimming space clean and safe for swimmers. Borates are pool chemicals that can be added to the water at a concentration of 30-50 parts per million (ppm) to help keep your device safe and sanitized without using chlorine. This will help create a pleasant swimming experience.

Borate is a non-toxic alternative to cyanuric acid, which will kill bacteria and other organisms in water. Not only is adding borate more affordable than other chemical treatments but it’s one-time and won’t decompose or decay while in use.

Borate can be added to water in order to break up calcium and magnesium ions that make your pool H2O hard, thus softening and smoother for swimmers with sensitive skin. This makes the water much softer, silkier, and smoother overall for everyone.

Another advantage is that borates prevent scaling from forming in your water. Scaling is an annoying issue which can do extensive damage to your pool.

Cleaning the surface of your pool can also become more challenging due to algae buildup, making it harder and costlier to do so.

Algae growth is a major concern for many swimming hole owners. Borate has been known to inhibit algae growth by interfering with its cellular metabolism and cell division.

Borates, like cyanuric acid, can help keep your pool clean by maintaining the pH level. This is especially useful for spaces prone to algae blooms.

Borates also help maintain the total alkalinity of your water, which is important as an imbalance can adversely affect other chemicals within it.

Furthermore, borates reduce chlorine usage by preventing algae from forming in the first place.

Muriatic Acid

Muriatic acid, also referred to as spirits of salt, is a widely-used swimming pool chemical. This dilute form of hydrochloric acid (HCI) is less hazardous for swimmers and other aquatic creatures than its undiluted counterpart.

Before adding muriatic acid to your pool, it’s wise to test its pH level first since too low can cause problems for swimmers. Remember, pH values are key factors in determining how effective chlorine works in your pool; keeping them within an ideal range will prevent algae buildup and other issues for swimmers.

If you’re worried about muriatic acid’s effects, adding baking soda to the water can help neutralize it. However, keep in mind that a low pH level may cause eye irritation and skin rashes for some people.

Another essential thing to consider is that muriatic acid can corrode metals, such as ladders and railings, including nuts and bolts. That’s why it’s essential to maintain your equipment and test the pH regularly before adding muriatic acid.

Be sure to follow the directions on your product and always dilute it in H2O before use. Otherwise, your mixture could spill and create a major mess.

One quick way to neutralize muriatic acid is by mixing baking soda and water together and keeping it nearby when working with it. Doing this allows you to quickly neutralize any accidental spills of muriatic acid.

Muriatic acid is an invaluable chemical, used to reduce the pH and alkalinity of your pool’s water. It’s also great to have on hand when you need to acid wash the surface, clean cartridge filters, or eliminate stains from the deck.

Keeping your pool clean is one way to ensure the best possible swimming experience for you, your family, and your guests. The right chemicals can help ensure your pool is safe and clean with minimal effort required from you.
