Pool and Spa Corrosion - An Atomic Point Of View

Doug Latta, Kim Skinner, and Que Hales, onBalance members, penned down an article in the Aqua Magazine, April issue. In the piece, they contended that the pH limit of 8.0 is very limiting. Furthermore, it is an inconsiderate directive to shut down pools when the pH is 8.0-8.5. The well-advised response is by Richard Young, from the commercial aquatics consultants. The column illuminates key issues concerning pH and Cyanuric acid. In a situation where the pH of the water is 8.0 when added a disinfectant with a lower pH, the after-effects have been debatable for years. Moreover, the article discusses crucial issues on the pH effect after adding a disinfecting compound necessary for the pool and spa water. The name of the disinfecting compound is the hypochlorous acid.

How Increase in pH Affects Pool and Spa Water

Medics and researchers have discovered that the HOCl compound is the activation agent that gets rid of viruses, bacteria, and pathogens. The feature further mentions that the nature of HOCI depends on several factors. CYA, pH, and the minimal effects of high levels of undissolved solids impact the resulting state/form the HOCl. Knowledge of chemistry is relevant to comprehend this information.

Hypochlorous Acid (HOCl) and Cyanuric Acid (CYA)

HOCl is a naturally unstable and very reactive compound. The introduction of CYA stabilizes the chlorine compound to reduce the impact of UV sunlight rays. HOCl is an excellent oxidizer and sanitizer because of its unstable nature. Stabilizing it with excess CYA levels (over 20-30 ppm) lowers the chlorine compound capacity to perform its role. Such levels may not affect backyard pools meant for decoration, but the effect differs for public pools and spas.

Your pool and spa water pH affects HOCl. When the pH reduces, more hydrogen ions are present to integrate with the Hypochlorous ions, enabling the formation of HOCl. When the pH increases, the hydrogen ions are minimal. This leads leading to the formation of more hypochlorous ions. This is the ionization of the HOCl process. It explains the definition of pH, which is an inverse logarithm of hydrogen ions in water or as Dr. Clifford White, usually referred to as doctor of chlorination described it, the dissociation of hydrogen ions.

Total dissolved solids (TDS) have a minor impact on HOCl compared to increased pH levels. The disintegration of hydrogen ions is an automatic and natural process. A higher pH reduces the formation of HOCl, while a lower pH increases the HOCl formed.

In summary, this means that when the pH is 8.0 or above, some level of disinfection will still take place. Pool and spa water does not require a lot of HOCl to disinfect. This explains why years back, chlorine residues of 0.2-0.4 were applicable for pH levels 7.4 to 7.8. With chlorine range of 1.0–3.0, the pH levels having little effect on the disinfection rates. Let us find out the reason health professionals prefer high Chlorine levels.

Oxidation of Hypochlorous Acid (HOCl)

Oxidation is the elimination of one or more electrons from a compound altering its molecular form. It is a very key process many are ignorant about. Many times, viruses and bacteria get into our pool and spa water. Organic compounds such as urine, sweat, saliva are also introduced and require elimination. Oxidation, in conjunction with HOCl, makes the above process possible.

You may have come across the term oxidation reduction potential (ORP). To illustrate, this is a millivolt measurement produced in water, taking electrons from a calibrated sensor. HOCl unstable nature now plays in during this process. It takes away electrons from another compound, disintegrating/oxidizing it. Oxidation changes some compounds to elements, for example, Nitrogen.

Oxidation reduction potential is the unit that measures chlorine efficiency in most pool chemical control systems. It is more about the quality rather than the quantity of HOCl. For instance, if the measurement is 3ppm with free chlorine present, the OPR reading may be 740mV at a 7.4 pH. If the pH rises to 8.0, the ORP will record a drop of about 40-50mV, and the new reading is 690-700mV. Adding effects of CYA when the levels are over 50ppm or the TDS is high is dangerous, especially when it comes to the increase in pathogens.

World Health Organization prescribes an ORP reading of 650mV as the smallest limit for efficient bacterium destruction. This is approximately 1ppm free chlorine in 8.8 pH water. The rise in pH causes a low ORP reading. The decrease in pH results in a high reading of the ORP. The rate of pathogen destruction is directly connected to the ORP levels. High levels of ORP increase oxidation of organic compounds in pool and spa water. If the organic compounds are not destroyed, they join with the HOCl forming combined chlorine referred to as chloramines that are distinctive organisms.

Increased pH levels cause oxidation of HOCl a rise in the concentration of HOCl ions. This lowers the ORP levels, making the destruction of the microbes slow, though still happen. When the ORP levels are high, the pathogens’ destruction is faster. Researchers concluded a survey on the pathogens’ inactivation at different ORP values to establish these facts.

Finally, the pH values should be at the desired levels to prevent a negative response, especially in active pools.

Leslie’s AccuBlue Home® Delivers First 10-Point At-Home Pool and Spa Water Testing Solution to Ensure a Safe 2024 Swim Season

PHOENIX, March 26, 2024 – Clear-looking pool water is mistakenly assumed to be safe for swimming, according to a recent survey conducted by The Harris Poll and commissioned by Leslie’s, the leading and most trusted consumer brand in the U.S. pool and spa care industry.

According to the poll, 71% of those surveyed believe that clear water is clean and safe for swimming. However, even clear water can contain contaminants that pose a danger to swimmers, and pool owners shouldn’t assume a pool is safe just because the water is clear.

A recent survey conducted by The Harris Poll on behalf of Leslie's found 71% of Americans mistakenly assume that clear pool water is clean and safe for swimming. Water testing is crucial to ensure healthy pool water, and Leslie's makes it easy with its new AccuBlue Home water testing program.
A recent survey conducted by The Harris Poll on behalf of Leslie’s found 71% of Americans mistakenly assume that clear pool water is clean and safe for swimming. Water testing is crucial to ensure healthy pool water, and Leslie’s makes it easy with its new AccuBlue Home water testing program.

The news arrives as Leslie’s launches its water safety education campaign for the 2024 swim season. Leslie’s is spreading awareness of the three primary tenets of pool safety: maintaining healthy and safe water, securing the pool area, and participating in swimming lessons and water safety education.

“As we head into the 2024 swim season, our aim is to help educate pool owners on the tenets of pool safety. Among those tenets is maintaining healthy water, and we make it easy for pool owners to test and treat their water, creating a safe environment for all,” said Clay Spann, SVP of Merchandising at Leslie’s.

“We aren’t surprised by these survey results, as there are many misconceptions related to pool water chemistry,” Spann said. “The only way to really know if pool water is clean, healthy, and safe for swimming is to check if the water is properly balanced and sanitized. To be certain of this, owners must regularly test the pool water’s chemistry makeup and precisely measure 10 different components, including pH, total alkalinity, calcium hardness, metals, phosphates, sanitizer levels, and more.”

The Leslie’s/Harris Poll survey also revealed that 71% of Americans who are responsible for maintaining a pool say keeping water safe is complicated, a misperception Leslie’s aims to correct with its AccuBlue® and AccuBlue Home® testing and treatment solutions.

Leslie’s makes water testing simple with its industry-leading AccuBlue technology — the only pool and spa water test that covers all 10 water chemistry components. In just 60 seconds, this free, in-store water test delivers a hardcopy printout with a water quality score and step-by-step customized water treatment plan to help keep pool water balanced. Pool and spa owners have relied upon this professional-grade testing over the past six decades, with more than 50 million tests conducted by Leslie’s store teams.

The same survey revealed that 81% of Americans who maintain their own pools wish there was a home technology solution for comprehensive 10-point pool water testing.

Last May, Leslie’s made water testing even easier and more convenient when the company launched its AccuBlue Home® membership program, which offers the same leading in-store testing technology, engineered into a compact at-home device. The AccuBlue Home testing device connects to the Leslie’s app to deliver a water quality score and customized water treatment plan to the user’s mobile phone or tablet.

Since its launch, AccuBlue Home has been embraced by pool owners, who value its convenience and accuracy. The membership program has earned a nearly five-star rating in member reviews with comments echoing exactly what it is designed to do: “takes all the guesswork out of testing your pool water” and “this little machine does everything the one in the store does.”

AccuBlue Home: How It Works
The technology is sophisticated, but the process is simple.

Users simply insert a pool water sample into the water test disk and place it into the AccuBlue Home testing device. They then open Leslie’s app on their mobile device to start the test, and AccuBlue Home does the rest. Light wavelengths pass through the water sample to precisely measure the water’s chemistry makeup, and the app delivers the water test quality score and a step-by-step customized treatment plan in just 60 seconds. The app enables pool and spa owners to order home delivery of chemicals needed to execute the water treatment plan.

An AccuBlue Home membership costs $50 a month, which includes the home testing device for free, as well as $50 in Leslie’s credits each month for purchases online, in app, or in stores. AccuBlue Home members can use their monthly credit to purchase any products from Leslie’s, including sanitizers and balancing chemicals, as well as floats, games, and other accessories to make the most out of pool days.

Marianne Trusty, president of Pool Magazine, said, “We’ve long recognized the importance of comprehensive 10-point testing for healthy and safe water and to maintain the longevity of pool equipment. Leslie’s has always been a leader, and it’s remarkable that they have driven their in-store technology into such a sleek device and an easy-to-use approach for pool and hot tub water testing.”

Virtual Pool Water Assistant
The AccuBlue Home device, measuring just 4.5 inches wide by 3.5 inches tall, is small, stylish, and self-contained, resembling a virtual assistant device — in this case, a virtual pool water assistant. It incorporates photometric testing technology with optical sensors, as well as a centrifuge, replaceable test disks, and more.
