One of the duties of your pool service is to monitor and adjust the chemicals in your pool. But what exactly are these chemicals and what do they do?
There are many different swimming pool chemicals that help keep your pool safe and clean. Some are used to control certain kinds of algae and bacteria that can build up in your pool’s water. There also are special kinds of chemicals that are specifically designed for use in hot tubs, spas, wading pools, and whirlpools.
Common Swimming Pool Chemicals
Chlorine is the most common type of disinfectant and sanitizer used in swimming pools. Usually, the chlorine will actually come from chlorinating agents that release their chlorine only when they dissolve in the pool’s water.
In larger pools, such as public pools or those at schools, chlorine gas is sometimes used.
Chlorine-based disinfectants can be either chlorinating liquids, dry chlorine, or liquid chlorine. Dry chlorine is composed of chemicals that come in a granular or tablet form.
Liquid chlorine and chlorinating liquid are solutions that dissolve in the water.
Other chemicals that keep your pool safe include inorganic chlorinating agents. These include calcium hypochlorite, lithium hypochlorite, and sodium hypochlorite. There also are organic chlorinating agents.
Usually, your pool service will use either organic or inorganic chlorinating agents because the two are not compatible. Care must be taken because if the same scoop or pail is used for both chemicals without cleaning in between, mixing or cross-contamination of these chemicals can form an explosive mixture.
That’s why it’s important to have a highly-skilled, professional pool service maintain your pool. While the chemicals they use will keep your pool safe and clean, they also can be highly dangerous if used by somebody without specific knowledge of their dangers.
Your pool service is knowledgeable about the handling, storage and use these and other chemicals.
