The water in swimming pools attracts our attention with its transparency and inviting sparkle; it seems like magic, doesn’t it? In a way it is, but it’s not always easy.
Maintaining pool water is a concern for those fortunate enough to have a pool at home. It’s not always easy, as there are many products that must be combined and administered correctly and precisely to achieve the desired effect.
One of the best-known chemicals for water treatment is chlorine, but it needs other, perhaps less well-known, partners to work properly and disinfect effectively. One such partner is isocyanuric acid, or CYA .
What is it for?
Isocyanuric acid, in the correct amount, has the power to stabilize chlorine levels and is used in outdoor or indoor (chlorinated, of course) swimming pools. Chlorine, a powerful disinfectant we all know, can be affected by UV rays , thus degrading its effectiveness . CYA acts as a shield and prevents the chlorine from breaking down, thanks to its ability to absorb sunlight.
This product simplifies chemical treatment by stabilizing chlorine levels, making maintenance less time-consuming and effortless , as it can be done at longer intervals. For example, instead of adjusting the chemical daily, it only needs to be done once or twice a week.
What levels should I maintain?
The ideal level of cyanuric acid is around 30-50 ppm ; other levels can be counterproductive or dangerous. At the same time, a free chlorine concentration of 1.5-2 ppm must be maintained continuously. This prevents the disinfecting power of the chlorine from diminishing.
For its effectiveness, we must also take into account the pH, which must be kept between 7 and 7.6.
Why is its control important?
Although not as well-known as chlorine, CYA is essential for professionals in the sector who recommend it to individuals. This has led to its widespread use, which must be monitored, because although it is very effective, if used incorrectly it can pose a health risk . Furthermore, its popularity has led to the emergence of potentially dangerous counterfeit products.
There is a direct relationship between increased levels of cyanuric acid and the time it takes to eliminate bacteria present in pool water. Therefore, if levels exceed recommended limits, the disinfection effect of chlorine can be reduced , posing a health risk to swimmers who may be affected by these bacteria.
For example, Cryptosporidium parvum, a microorganism that affects the intestinal health of humans, is found in polluted water that lacks proper maintenance. Furthermore, it is resistant to some chlorine concentrations, so we must control, stabilize, and supplement it with the correct level of chlorine-based ammonia (CYA).
