What chemicals do you use in a swimming pool?

Chlorine: One of the most common and effective chemicals used to disinfect pool water, killing bacteria and other microorganisms. It also oxidises organic matter, helping to keep the water clean and clear.

Bromine: An alternative to chlorine, also used as a disinfectant. It is more stable in sunlight than chlorine and can cause less eye irritation.

pH balancers: Used to adjust the acidity or alkalinity of pool water. Maintaining a proper pH level (between 7.2 and 7.8) is important for the effectiveness of the disinfectant and to prevent corrosion of pool equipment.

Alkalinity increasers: Raise the alkalinity of pool water, which helps stabilize the pH level and prevents corrosion.

Calcium hardness increasers: Increase the calcium content of pool water, which helps prevent corrosion and can also help to make the water feel softer.

Cyanuric acid: Used to stabilize chlorine in outdoor pools, reducing its degradation by sunlight.

Algaecides: Prevent the growth of algae, which can make pool water cloudy and green.

Flocculants: Aid in the settling of small particles and debris, making them easier to filter out.

Clarifiers: Help to clear cloudy pool water by causing small particles to clump together and settle.

Shock treatments: High doses of chlorine or other disinfectants used to kill bacteria and oxidize contaminants.

The specific chemicals used and their dosage may vary depending on pool size, water temperature, bather load, and local regulations. It is recommended to consult with a pool professional or refer to the manufacturer's instructions for the proper use and handling of pool chemicals.
