What does cyanuric acid do in a pool and its benefits?

What does cyanuric acid do in a pool? Cyanuric acid is a chemical compound found in most pools. It's also known as ferricyanide, which gives it its characteristic color. That color is brownish-purple, because the molecule has a cyano group attached to the nitrogen atom of an iron atom. Cyanuric acid is often added to pool water to prevent algae growth, by killing the cells formed by blue-green algae. Most swimming pools add cyanuric acid at levels of 10 parts per million (ppm) or more in order to be compliant with federal standards for safe swimming water levels.

Uses of cyanuric acid do in a pool

1. As a stabilizer

What does cyanuric acid do in a pool? Cyanuric acid is a salt that is used as a stabilizer. It increases the pH of its surroundings, including animal tissues and some bacteria. It is usually used as a fungicide and disinfectant, though it's also sometimes used to control algae in ponds and water gardens.

2. To prevent algal growth

In addition to its more obvious purpose, cyanuric acid can also be added to pool water in order to prevent algae from growing, because it kills the cells produced by blue-green algae (also known as cyanobacteria). This allows other types of algae to flourish, thereby giving the water a more natural appearance.

3. To balance chemical processes

Algae eventually consumes oxygen and other nutrients in the water. The cyanuric acid (and other chemicals) consumed by the algae is released back into the water as products of their decomposition. This helps to keep pools from becoming depleted of oxygen and basic nutrients, which could potentially lead to the growth of unpleasant organisms such as bacteria and fungus.

4. To treat ocular infections

Cyanuric acid can be used to treat ocular infections (such as conjunctivitis). It works by killing cells in the eyes, which reduces irritation and improves healing. This may sound counterintuitive, but it is actually less invasive than other treatments, such as viruses that suppress inflammation and tissue damage.

5. To treat tapeworms

hat does cyanuric acid do in a pool? Cyanuric acid is also sometimes used to treat tapeworms. Here, it acts as an acaricide, a substance that kills parasites by disrupting the life cycle of their eggs. The organism that's affected by cyanuric acid is the cysticercus (a larval form of the tapeworm). As noted above, because cyanuric acid works in several ways besides killing adult organisms, it can be used in a variety of different situations where these organisms are present.

6. To kill fish eggs

Algae can also consume some of the products produced by phosphorous-based fertilizers, though this often isn't an issue with pool water because it's particularly rich in phosphorous (this element is prevalent in most house plants). Still, cyanuric acid is sometimes added to ponds and other water gardens in order to increase their resistance to algae growth. This is especially common when the water garden is not as deep as a swimming pool, or if its owners want the pond to accumulate more oxygen, or if they want it to appear more natural.

7. To treat sweating

Cyanuric acid was once used to treat excessive sweating in people. It's now considered ineffective and is prescribed less frequently. It can cause the skin to become dry, irritated, and cracked. It can also damage the nervous system, especially when it's applied directly to the skin.

8. To remove industrial pollutants

What does cyanuric acid do in a pool? Cyanuric acid has been used to remove a number of different industrial pollutants from water. These include benzene (a compound used in plastics manufacturing), napthalene (a substance that lubricates industrial machinery), and phenol (an anti-bacterial disinfectant).

9. To remove pesticides

Various other chemicals are also sometimes used to remove pesticides from water. These include benzene, carbon tetrachloride, and chlorine. Carbon tetrachloride is a known carcinogen, so is generally not recommended for use in pool water. It does have some other advantages that make it an appealing choice for a few situations, such as killing algae or pools contaminated with petroleum products.

10. To treat excessive copper

Cyanuric acid has been used to treat people who have excessive levels of copper in their blood, especially those who have a genetic response to the metal. The therapeutic value of this treatment has been disputed, though it may still be used for some people with no other treatments available.

Conclusion

What does cyanuric acid do in a pool? The chemistry of cyanuric acid has been quite well researched, as indicated by its wide variety of uses. It's used to treat a number of diseases, both in people and in animals, and its benefits have been proven in numerous scientific studies. The chemical properties that make it so effective are what make it dangerous at higher concentrations.
