If left unprotected, UV rays can destroy up to 90% of the chlorine in your pool in just two hours! Not only is that a huge waste of money, but it also leaves your pool without any sanitizing abilities. To combat this, Cyanuric acid should be measured occasionally and balanced when needed. How do you increase Cyanuric Acid (CYA) in Pools?
- Test current cyanuric acid level (If CYA is below 60 ppm)
- Purchase cyanuric acid (CYA)
- Calculate required amount
- Pre-dissolve CYA in warm H2O
- Add CYA to pool skimmer
- Run pool pump for 24 hrs.
- Retest after 48 hours-adjust as needed
- Use a stabilized chlorine like sodium dichlor or trichlor, to sanitize your pool
Suppose your Cyanuric Acid level is above 60 ppm. In that case, it can skew Total Alkalinity results in water tests, making it appear higher than it is so balancing this important chemical is critical for maintaining your pool and cost savings.
Introduction
Keeping a swimming pool clean and safe goes beyond adding chlorine and removing leaves. Cyanuric acid plays a key role in pool chemistry, but many people don’t realize its importance. This chemical compound works as a stabilizer for chlorine in outdoor pools. People often call it a pool stabilizer or conditioner. Cyanuric acid impacts chlorine by protecting it from breaking down due to the sun’s UV rays. This means the chlorine stays effective in sanitizing the pool water.
Cyanuric acid is key in your pool water to keep chlorine levels stable. Without it, the sun’s UV rays would break down the chlorine you add leading to poor sanitation and unsafe swimming. By protecting chlorine cyanuric acid helps maintain steady and effective chlorine levels, which is crucial to stopping harmful bacteria and algae from growing.

By sticking to these rules, you’ll keep your pool clean, safe, and fun for everyone who swims in it.
How to Increase Cyanuric Acid In Pools
When CYA levels in your pool drop below 30-50 ppm, you need to boost them to keep chlorine working well to clean the water. You can add CYA with a stabilizer or use chlorine products that already have it, like trichlor or dichlor.
If you choose a CYA stabilizer, figure out how much you need based on your pool size and current CYA amount. Then, mix it in a bucket of water or put it in the skimmer to spread it around.
Make sure you have good water circulation to spread the stabilizer in your pool. Another option is to use chlorine products that already have stabilizers in them. These clean the water and increase CYA levels at the same time. Always follow what the product label says about how much to use and how to handle it. It’s key to test your pool often to keep an eye on CYA levels. This helps you avoid adding too much stabilizer, which can make chlorine less effective. By adding stabilizers, you can keep CYA levels balanced. This keeps your pool water clean and safe for swimming.
Why Increase Cyanuric Acid in Pools
Raising cyanuric acid (CYA) levels in pools play a key role in keeping chlorine stable and water clean. CYA works like a barrier for chlorine stopping the sun’s UV rays from breaking it down too fast. If CYA levels are too low, chlorine fades leaving the pool open to germs, algae, and other nasty stuff. When pool owners keep CYA levels between 30-50 parts per million (ppm), chlorine stays active longer. This means they don’t need to add chlorine as often and the pool stays protected from harmful microbes. The right CYA levels help keep pool chemistry in check, make chlorine work better, and in the end, create a safe and fun place to swim.
Understanding Cyanuric Acid
Definition and Chemical Properties of Cyanuric Acid
Cyanuric acid, chemically known as 1,3,5-triazine-2,4,6-triol, is an organic compound that forms a white, crystalline powder. It is relatively soluble in water and is commonly used in the pool industry due to its ability to stabilize chlorine. Cyanuric acid works by forming weak bonds with chlorine molecules, which protects them from rapid degradation by ultraviolet (UV) rays from the sun.
Role of Cyanuric Acid in Pool Water
Cyanuric acid plays a critical role in maintaining the effectiveness of chlorine in pool water. Here are the primary functions it serves:
- Stabilizing Chlorine: Chlorine is the most common sanitizer used in swimming pools, but it is highly susceptible to breakdown when exposed to sunlight. Cyanuric acid acts as a stabilizer by bonding with free chlorine in the water, reducing its photolytic decomposition. This means that the chlorine remains effective for a longer period, allowing it to maintain the pool’s sanitation.
- Protecting Against UV Degradation: UV rays from the sun can destroy up to 90% of free chlorine in just a couple of hours. Cyanuric acid absorbs and reflects UV light, protecting chlorine from being rapidly broken down. This ensures a more consistent level of chlorine in the pool water, leading to better protection against bacteria and algae.
Optimal Levels of Cyanuric Acid in a Pool
Maintaining the correct level of cyanuric acid in your pool is crucial for effective chlorine stabilization without compromising water quality. The optimal range for cyanuric acid levels in pool water is typically between 30 and 50 parts per million (ppm). Here’s a breakdown of why this range is recommended:
- Below 30 ppm: At levels below 30 ppm, there is insufficient cyanuric acid to effectively protect chlorine from UV degradation. This results in rapid loss of chlorine, requiring more frequent additions to maintain proper sanitation.
- 30 to 50 ppm: Within this range, cyanuric acid provides adequate protection for chlorine, significantly reducing the rate at which it breaks down under sunlight. This helps maintain consistent chlorine levels and ensures effective sanitation.
- Above 50 ppm: Levels above 50 ppm can lead to diminishing returns. High cyanuric acid levels can inhibit chlorine’s sanitizing ability, making it less effective against bacteria and algae. Additionally, if levels become excessively high, it may necessitate partial draining and refilling of the pool to dilute the concentration.
By keeping your cyanuric acid levels within the optimal range, you can ensure that your pool water remains clear, clean, and safe for swimming. Regular testing and careful management of cyanuric acid are essential components of effective pool maintenance.
Testing Cyanuric Acid Levels
Testing cyanuric acid (CYA) levels in your pool often plays a key role in keeping a balanced and safe place to swim. The right amount of CYA helps chlorine work well to clean the pool water guarding against harmful germs and algae. If you don’t check CYA levels regularly, they might drop too low making chlorine less effective, or climb too high leading to over-stabilization that can stop chlorine from cleaning. By keeping an eye on CYA levels all the time, you can act to fix any issues and keep your pool water balanced and safe.

Monitoring and Maintaining Cyanuric Acid Levels
Stabilized chlorine: Also known as sodium dichlor and trichlor, stabilized chlorine is suitable for use in outdoor pools. Since Cyanuric Acid is already compounded into this form of chlorine, you don’t have to worry as much about sun exposure.
When you first fill your pool, put in conditioner to boost your Cyanuric Acid levels to the lower end of the ideal range of about 30 ppm. As you use stabilized chlorine, your Cyanuric Acid levels will go up over time. For the most part, Cyanuric Acid levels decrease with a lot of splash-out, a pool leak, or during backwashing. Check your water to keep an eye on Cyanuric Acid levels in your pool.
Keeping an eye on and taking care of cyanuric acid (CYA) levels in your pool has a big impact on how well chlorine works and how clean the water stays. It’s a good idea to check these levels every 1-2 weeks when people are swimming a lot. This way, you can spot any problems and fix them before they mess with how clean your pool is.
When CYA levels drop below the ideal range of 30-50 ppm, sunlight breaks down chlorine, which means you need to add chlorine more often to keep the water safe.
On the other hand, CYA levels above 50 ppm can make chlorine less effective, which might lead to algae and bacteria growth. To keep CYA levels right, you should add a stabilizer when needed, but be careful not to use too much. If the levels get too high, you can lower them by draining some pool water and adding fresh water.
Also, regular pool care like cleaning filters and making sure the water moves around well helps cyanuric acid do its job of keeping chlorine stable. This keeps your pool water clean and safe for swimming.
When you’re managing cyanuric acid (CYA) levels in your pool, you might make some common mistakes that can throw things off balance and make upkeep more difficult. One mistake people often make is using too many stabilizers. This can cause CYA levels to get way too high, which makes chlorine less effective. When this happens, you might need to drain some of the pool water and add fresh water to get things back to normal.
On the other hand, not adding CYA or testing too can make chlorine break down from UV rays, which means you need to add it more often to keep the water clean. Another mistake people often make is not mixing the water well after putting in the stabilizer, which leads to it not spreading and giving wrong test results. Also, using chlorine products that already have stabilizers in them without thinking about how they affect CYA levels can make the concentration go up over time without you realizing it.
To steer clear of these problems, make sure you test, stick to the manufacturer’s guidelines for using stabilizers, and keep up good circulation and filtration. If your CYA levels get too high, you can use a store-bought cyanuric acid reducer or replace some of the water to bring down the concentration. By keeping an eye on things and tackling issues right away, you can maintain balanced and safe pool water.
Conclusion:
Keeping the right cyanuric acid (CYA) levels plays a crucial role in making sure chlorine stays effective in cleaning your pool, guarding against bacteria and algae, and creating a safe place to swim. Testing often and managing CYA levels helps to avoid common problems like chlorine breaking down too fast and over-stabilization, which can hurt water quality.
To keep your pool water balanced and healthy, test CYA levels every 1-2 weeks when swimming season is in full swing. Use stabilizers, and watch how stabilized chlorine products affect CYA levels. Make sure to circulate water after adding stabilizers, and clean your filters often to help manage water. If CYA levels get too high, think about draining some water and refilling the pool or using commercial reducers to bring the concentration back to the right range. By sticking to these tips, you can keep your pool clean, safe, and fun for everyone to enjoy.
