Swimming Pool Chemicals

An important part of swimming pool maintenance involves adding the proper pool chemicals to guarantee clean and safe water. Vital for pool sanitation, swimming pool chemicals will help keep pool water clear, and potential hydrogen (ph) levels balanced. Potential hydrogen measures the level of acidity and alkaline found in pools, the strong smell of chlorine indicates that ph levels have not been balanced.

Pool maintainance

Chemical imbalances in pool water is unhealthful for swimmers, and can damage the pool’s pumping, filtering, or heating system. The ph levels in your pool should be checked two or three times per week. There are a variety of pool chemicals that can treat the water in your swimming concrete pool, including shocks and balancers, sanitizers, stabilizers, and algaecide. Following is a list of common swimming pool chemicals and their uses.


An Algaecide treatment will kill pre-existing algae and prevent it from recurring. Available in liquid or tablet form, algaecides are formulated to eliminate different types of algae. Other products such as algae inhibitors, or algaestats can be used to halt green, yellow, or black algae growth. Algaecides must be used cautiously while following professionals or manufacturers directions. Improper use of algaecide can stain pool walls or flooring.


Used to adjust elements in swimming pool water, balancers should be added when problems such as low pool ph levels occur. Some balancers for pools include water hardeners and chlorine neutralizers, ph increasers made from soda ash, sodium bisulfate or muriatic acid is used to reduce ph levels, and increasers or reducers are for calcium hardness.


Available in grain, stick, or tablet form, chlorine will disinfect and sterilize your swimming pool water. Another form of pool disinfectant known as bromine kills bacteria and other germs found in concrete pools water. Many pool owners prefer bromine, it is more expensive, but the smell is not as strong as chlorine. Bromines and chlorine can be released automatically in pre-set dosages, or may be dispensed by a flotation device. Commonly known as pool sanitizers, chlorine and bromine should not be mixed.


Widely known as water pool conditioners, stabilizers improve the performance of chlorine that has been added to swimming pools. Sunlight exposure will cause chlorine to deplete very quickly, adding stabilizers will help stop chlorine depletion. Stabilized chlorine refers to chlorine products with built-in stabilizers that can be added to control the ph levels in swimming pool water.

To keep your pool clear and clean, check chemicals every week to determine if ph levels should be raised or lowered. It will be necessary to shock your pool at the beginning of each season to ensure that hair, skin, and eyes are safe from irritation. Pool shock will help eliminate powerful odors and irritants with adequate amounts of chlorine.

Caution: You must always seek professional advice before using any swimming pool chemicals.
