Myths About Residential Gas Chlorination

Gas chlorine is chlorine in its purest form, and is the base element used in the production of all other swimming pool chlorine compounds, including tablets, powders, and liquids. It is used extensively in water treatment throughout the world due to its efficiency both as a sanitizing agent and as an oxidizer. Since gas chlorine does not contain any of the salts or additives found in all other chlorinating compounds, it does not promote the rapid buildup of these elements in the pool water. Although most large public and semi-public pools use gas chlorine via automatic feed systems, the use of gas chlorine in residential swimming pool water treatment is limited to a relatively small number of qualified pool service firms across the nation who are licensed, registered, and specially trained in its handling and use. Gas chlorine is an EPA-registered product, and its use has the approval of the National Spa and Pool Institute (NSPI). Gas chlorine has been used safely and reliably in residential pool water treatment for more than 50 years. No other chlorinating compound can compare to gas chlorine. It is the most efficient means of treating pool water. It significantly reduces the hardening of water, due to its purity. But, as its use is limited to a handful of extremely specialized pool firms, gas chlorine has the distinction of being perhaps the least understood chemical in the swimming pool industry. This lack of understanding has allowed a proliferation of inaccurate and misleading statements to be disseminated regarding gas chlorine from within the swimming pool industry itself. The National Association of Gas Chlorinators (NAGC) offers this treatise in an effort to address these statements and dispel the myths associated with the process of gas chlorination.
The following are typical areas of misunderstanding about gas chlorine:
Myth #1: Gas chlorination is illegal.
Myth #2: Gas chlorination damages pools and equipment.
Myth #3: Since gas chlorine is acidic, it has to be bad.
Myth #4: Gas chlorine is too dangerous.
Myth #5: Gas chlorine is used as a deadly war gas.
Myth #6: Gas chlorinators maintain chlorine levels that are too high.

So what are the advantages of gas chlorination?

Chlorine has actually been one of the most beneficial chemicals used in the world, not only through its use in water purification, but also through its use in the production of necessary medicines and disinfectants. A world without chlorine would be a world with typhus, dysentery, and cholera. Our world with chlorine is a much nicer, more sanitary place. Gas chlorine is the most efficient method of treating water, and it is the only pool sanitizer that does not add salts, additives, or inert ingredients to water. Harmful bacteria and fungi are effectively destroyed, along with algae infestations. The use of gas chlorination by a qualified service company completely negates the handling and storage of dangerous pool chemicals in or around the home.
How do I select a gas chlorine company?
As with the selection of any service for your home, you should check references before engaging a service company. Since residential gas chlorine companies are required to have establishment and registration numbers from the EPA that is a good place to start. Things to check include the company's length of time in business, experience, knowledge of their product, and what their service specifically does or does not include. Please feel free to call the National Association of Gas Chlorinators (NAGC - 714-951-1733) for any additional information you desire relative to the benefits of using pure gas chlorine in your pool.
Notes from industry experts:
"If properly applied or administered in accordance with the Chlorine Institute and all other applicable codes and regulatory requirements, gas chlorine is a viable, effective pool sanitizer/oxidizer and has no greater potential for pool damage than any other chlorine sanitizer." The Plasterer's Council, an industry trade association affiliated with the National Spa and Pool Institute, Southern California Chapter.
"We have no reason to believe that gas chlorine has any more of an adverse effect on solar blankets than any other sanitizer, assuming all other factors, i.e. pH, total alkalinity, etc. are maintained at generally prescribed levels." Cantar Corporation, a manufacturer of "blue bubble" solar blankets.
"We have many Polaris' working in pools with all commonly used chemicals, including those serviced by chlorine gas without problems being caused to the Polaris." Polaris Pool Systems
"When administered properly, there is no discernible difference between gas chlorine and other forms of chlorination on the Kreepy Krauly unit." Kreepy Krauly
