What is cyanuric acid for pools-Factors to Consider

What is cyanuric acid for pools? Cyanuric acid, also called chlorine stabilizer or conditioner, is a compound that slows the degradation of free and combined chlorine in pool water. Free chlorine is what you get when you add bleach or another oxidizing agent to the water. It's an unstable form of chlorine.

Combined chlorine forms when free chlorine mixes with dirt, oils, urine, sweat, or other contaminants in the water. Combined chlorine is also unstable and will degrade to form free chlorine, which then degrades further into things that are either useless or harmful to swimmers' health.

What is Cyanuric Acid for Pools

Cyanuric acid helps keep combined chlorine from degrading too quickly. It absorbs excessive amounts of combined chlorine, so it doesn't degrade and become free chlorine. The amount of cyanuric acid needed varies based on the water temperature, bather load, and pool size.

In pool water, cyanuric acid should be between 30 and 50 parts per million (ppm).You can test it with a test kit or test strips as part of regular pool maintenance. You can also find it in products that treat pools, available at pool supply stores or online.

Advantages of Using Cyanuric Acid in your Pools

One advantage of using cyanuric acid is that it helps keep the chlorine in your pool water from breaking down. This means you can use less chlorine to disinfect your pool because fewer contaminants will kill. Because you need lower levels of free chlorine, combined with cyanuric acid, you will also reduce or eliminate eye and skin irritation and the unpleasant smell of chlorine around your pool.

When should you add Cyanuric Acid to your Pool?

You should add cyanuric acid when you start a pool or raise the water level. You should also check it throughout the season and add more if needed to maintain a concentration of 30-50 ppm.

Be sure your free chlorine is at least 1 part per million higher than combined chlorine, which generally works out to about three ppm total chlorine.

How Often Should you Add Cyanuric Acid to your Pool?

You should add cyanuric acid to your pool at least once a season, typically in spring, before opening the pool. If you use a lot of combined chlorine, you should add it more often to maintain 30-50 ppm.

In cases where pools have experienced a water loss or been drained, you may need to add more during the summer months.

You can test for cyanuric acid with a kit or test strips available at pool supply stores, online retailers, and local dealers.

Cyanuric Acid Dosage Rate

In most pools, the dosage rate of cyanuric acid ranges from 20 to 40 pounds per 10,000 gallons of water. In other words, if you have a pool that holds 20,000 gallons of water, you would need 400 to 800 pounds of cyanuric acid at a dosage rate of 40 ppm.

Other Tips about Cyanuric Acid

Because it prevents combined chlorine from breaking down quickly and irritates the skin, some pool owners add more cyanuric acid than is needed. If you have a high bather load, you may want to reduce the cyanuric acid level by ten ppm. By doing so, you can avoid increased irritation from more free chlorine and at least save on some of the cost of the additional chemicals.

Can You Swim in a Pool with High Cyanuric Acid?

As long as you maintain a free chlorine-to-combined chlorine ratio of at least 3:1, it should be safe to swim in a pool with high levels of cyanuric acid. You can test the safety of your pool by using test strips or testing kits available at pool supply stores and online.

What are the Side Effects of Cyanuric Acid?

Cyanuric acid serves a valuable purpose in pools, but it can have side effects. These include skin and eye irritation and dry, flaky skin if the level is very high. In extreme cases of ingestion or over-exposure to cyanuric acid, you may experience more severe symptoms, such as nausea and vomiting.

How to Remove Cyanuric Acid from Pool Water?

Because cyanuric acid is a chemical, you need the help of pool professionals to remove it. Suppose your cyanuric acid level becomes too high, or you've had an unusually high number of bathers that may have dramatically increased the level. In that case, you may need to drain some of the water and replace it with fresh pool water.

Conclusion

What is cyanuric acid for pools? Cyanuric acid is a beneficial chemical in your pool's water. In general, it is a good idea to add cyanuric acid as you open your pool in the spring and as needed throughout the pool season.
