The Relationship Of Ph Chlorine And Cyanuric Acid Levels

How To Balance CYANURIC ACID In Your Pool | Swim University

If your pH goes down, the effectiveness of your chlorine goes up. This is commonly understood. But in the presence of cyanuric acid, the relationship between pH and chlorine is substantially altered. For example, if your pool maintains a pH of 7.2, about 63 percent of the chlorine is in its active form. If you introduce just 30 ppm of cyanuric acid to the pool, this drops to 1.6 percent of the chlorine being in its active form.

Depending on the size of a pool and jurisdiction, public pools have regulated limits for cyanuric levels of 40-100 ppm to prevent problems from over chlorination or unbalanced pH. Although cyanuric acid offers a low level of toxicity without any serious health concerns, having high-levels of this chemical in a pool puts people at risk because of the chlorines diminished ability to kill bacteria and viruses. In Florida, the Department of Health states that a pools cyanuric levels may not exceed 100ppm to prevent gastrointestinal illness, skin rashes, and other diseases.

Despite these ongoing issues, the industry has never found a cost-effective solution and environmentally safe way to remedy this problem.

On top of the pool chemistry problems, draining your pool presents environmental hazards:

If you were able to manage the levels of cyanuric acid in your swimming pool without draining it all these issues could be avoided.

A Beginner’s Guide To Using Pool Stabilizer

Pool stabilizer contains cyanuric acid or s-triazintrione, which combines with the chlorine in your swimming pool, making the chlorine less likely to react to sunlight. As a result, your chlorine will last longer so you can use less. This easy to use, odorless stabilizer puts the levels right where it should be and will maintain that level.

Cyanuric acid likes to go by a lot of different names in the pool industry such as CYA, pool stabilizer, pool conditioner, or chlorine stabilizer. Whatever you choose to call it, this chemical has played an integral part in pool maintenance creating a $300 million a year industry since its invention in 1829.

A possible exception is when the total alkalinity of the pool water is less than 80 ppm and the cyanuric-acid level is over 60 ppm. If both these conditions exist, the operator should determine the carbonate alkalinity by subtracting one-third of the cyanuric acid level from the total alkalinity.

I was given the opportunity to try the HTH Stabilizer recently in my 22′ vinyl pool and I was not disappointed. Anyone who has a pool knows they have to keep up with their chlorine levels and if your CYA levels are not in range you lose chlorine to sunlight.

What Should Be The Levels Of Isocyanuric Acid In Salt Pools

Saltwater pool manufacturers recommend keeping cyanuric acid levels around 60-80 ppm.

This is slightly higher than the 30 to 50 ppm range recommended for non-salt water pools.

And if you live in an area where your pool gets a lot of direct sunlight, you can even consider boosting your cyanuric acid up to 80-100 ppm.

If the Cyanuric Acid level is higher than 100 ppm for an outdoor salt water pool and over 50 ppm for an indoor salt water pool, then you will need to reduce the level. You can do this by partially draining the pool and then replacing it with fresh water.

Remember that by following this procedure you are reducing the salt level in your salt water pool too. Make sure to put back the salt lost due to draining. The recommended salt level for a Aqua Rite Electrolytic Chlorine Generator from Hayward is 2700-3400 ppm.

Simple Steps: How To Raise Cyanuric Acid In A Swimming Pool

Maintaining the levels of the chemical in an ideal range is one of the obligatory jobs that every pool owner should do on a regular basis. Of course, the purpose of this process is to make sure that you have a safe environment to swim and chill. As you may have known that if the chlorine level is below the ideal range, you will face an algae problem and when the alkalinity is too high, you will find some stains in your pool.

Talking about cyanuric acid, its chlorines best friend which works to stabilize the level of free chlorine in the water. Raising cyanuric acid also known as pool stabilizer is not a hard job, but you have to do it carefully to prevent worse problems from happening. Below we have a quick tutorial on how to raise cyanuric acid in a pool.

How Long Does It Take For Cyanuric Acid To Dissolve

The time it takes for cyanuric acid to dissolve is 2 to 5 days. Its important to be patient during this time and wait for it to fully dissolve before adding more cyanuric acid to the water. Cyanuric acid levels will continue to increase until all of the chlorine stabilizer has completely dissolved.

Cyanuric Acid: A Discussion On Chlorine Stabilizer

How To Add Chlorine & Cyanuric Acid (Stabilizer/Conditioner) To Your Swimming Pool

Welcome, students. Ive prepared a lecture today on the chemical compound Cyanuric Acid 3.

You may know CYA as pool stabilizer or conditioner. This curious chemical seeks out and attaches itself to the chlorine molecule. In doing so, it acts as a sun shield, absorbing sunlight, and reducing the suns degradation to your chlorine.


The chemical was discovered in 1829, by Friedrich Wöhler a German chemist. It was not until the 1950s, however, that a class of disinfectants known as chlorinated iso-cyanurates were developed. Soon after, savvy chlorine manufacturers began adding it to stabilize chlorine tablets.

Cyanuric acid that is sold as pool stabilizer or conditioner is a white, flaky powder, similar in appearance to calcium chloride. It is a weak acid, and is not corrosive or considered hazardous.

How To Reduce Cya In Pools

What can you do if your CYA levels are already high? Can CYA levels be reduced in a pool?

Yes, the most economical way to lower CYA is to partially drain and dilute the pool with fresh water. Consult a pool professional if you want to drain more than 1/3 of your water, because there are risks with hydrostatic pressure and other concerns. There are also some specialized filters that exist to capture CYA and remove it from water, such as reverse osmosis . RO is far more costly, but it may be the best option for people in regions of the country that are unable to drain their pools.

It really just comes down to cost and risk. Significant draining has risks and should only be done by a pool professional, so dilution over time is often the best option. The alternatives to draining your water are to 1) pay big money for filtration, or 2) try to manage the pool with high levels of CYA. Neither of those two options are as easy or affordable as replacing water with fresh water.

The bottom line: keep CYA levels low enough to manage sanitation and maintain LSI balance. If your CYA is too high, draining and diluting is the most cost effective means to reduce CYA in your pool.

What Levels Of Cyanuric Acid Are Optimal

Even a small amount of cyanuric acid is good for your pool, so if youre afraid of going overboard, you can opt for adding trace amounts.

But the optimum level is considered 30-50 ppm .

Any higher and it will keep the chlorine from being killed by the sun, but it will lose virtually all effectiveness in killing bacteria.

The Bottom Line On Cya And Your Pool

How to Use Swimming Pool Conditioner, Cyanuric Acid

Pool care means keeping your levels balanced, including pH, sanitizer, and CYA. Chlorine is vulnerable to the sun, and CYA can protect it, but the trade-off is lower efficacy of your chlorine.

Striking the right balance, starting around 50 ppm and never over 100 ppm, is essential.

If levels in your pool are too low, under 30 ppm, youll need to get a lot of chlorine to adjust. If theyre too high, youre going to need to dilute them, by at least partially draining and refilling your pool.

Your familys healthy use of your pool depends on your sanitizer, stabilizer, and pH working together to keep your water safe and clear.

Is It Safe To Swim In A Pool With High Cyanuric Acid

A high cyanuric acid level doesnt have any serious health implications, and it is not harmful in most cases.

But the problem is that a high pool CYA level reduces your chlorines effectiveness, which is essential for killing bacteria and viruses in your pool.

So while the CYA level does not directly affect your health, it can indirectly cause health problems due to a lower level of chlorine in your pool.

In short, it is not a good idea to swim in a pool with a high CYA level.

Cyanuric Acid proper levels of “Cyanuric Acid” helps protect against chlorine loss caused by sunlight. 30-100ppm Cyanuric Acid: Cyanuric acid, also called “stabilizer” or “conditioner, ” makes chlorine more stable when exposed to the sun’s ultraviolet rays. It is like sunblock for your sanitizer, preventing it from degrading as quickly as it would otherwise. Without cyanuric acid, your chlorine level can drop from the ideal range to zero in less than two hours. On the other hand, if cyanuric acid is too high, it can cause a high level of total dissolved solids , and cause chlorine to be inefficient. Two types of chlorine compounds, dichlor and trichlor, already contain some cyanuric acid. The level of cyanuric acid will build up with the continued use of either of these sanitizers. If using any other form of chlorine, you will need to add cyanuric acid separately in order to stabilize the chlorine. The acceptable level of cyanuric acid is 30 to 150 ppm , with an ideal level of 30 to 50 ppm .

Cyanuric acid swimming pool what is it, how to lower it, raise it and slow its rise: chlorinated isocyanuric acids are a weak acid composed of stabilized chlorine , of limited solubility in water that is incorporated to stabilize the chlorine in the water. In addition, although it is essential for the maintenance of the pool, it is really little known among the owners of private pools, it is even little mentioned in the specialist swimming pool stores despite its vital importance.

En Ok Pool Reform within Maintain pool water guide we present the article: What is cyanuric acid in swimming pools.

How Does It Get In My Pool

Given these issues, it is very important to maintain a proper level of CYA in the swimming pool. The most common place we find cyanuric acid is in the 3-inch chlorine pucks that most people use to sanitize their pool.

A single 3-inch chlorine tablet weighs 1/4 of a pound and is 50 percent CYA per puck. That leaves us with an eighth of a pound of CYA per one chlorine tablet.

This may not seem like a lot, but the thing with CYA is that it does evaporate off with normal evaporation. When your pool water evaporates off, roughly 1/4 inch per day, the cyanuric acid is left behind, causing CYA to build up over time.

It is not uncommon here in Austin to see CYA levels reach well over 150-200 ppm, which is extremely high.

A Quick Chemistry Refresher

Cyanuric acid is a chemical compound in the triazine family, which basically means that its chemical makeup includes three nitrogens and three carbon atoms. It forms a weak and temporary bond with chlorine, which affects the chlorine more than the cyanuric acid itself. Well discuss that in a bit.

Chemically speaking, sodium dichlor is made up of one cyanuric acid molecule with two chlorine atoms and one sodium atom. This combination forms stable chlorine, which comes as a colorless solid.

    Solve The Problem By Emptying It Partially Or Completely

    Although how to lower cyanuric acid in the pool will depend on each case, make a point that if the pool has a high concentration of isocyanuric acid, the only way to lower it is by emptying the pool.

    In the case of obtaining high levels of cyanuric acid in swimming pools, it is very difficult to reduce since it is degraded very slowly. So the best alternative will be empty the pool and renew the water.

    The resolution of the water relay will depend on the present values of cyanuric acid.

    Mostly as we have said before, the verdict will be executed according to:

    • Before everything, you must replenish all the pool water if you sustain cyanuric levels above 0 100ppm.
    • or to the contrary, partially replace and dilute your pool water if levels are above 80 ppm

    Cyanuric Acid: Is That Whats Missing From Your Pool

    To save a little money, you decided to go the DIY route with your pool. You did the cleaning. You handled the maintenance issues. You mixed in the chlorine and other chemicals to keep the pool pristine.

    At first, it seemed to work pretty well. The kids had lots of fun, and you got to enjoy not paying for a service, putting a small chunk of change back into your pocket. Not too bad.

    After a little time passed, though, you noticed that you were starting to get some algae growth. Later, you discovered that the pool was kind of green and cloudy. Then, after a bunch of kids came over and swam for the afternoon, several of them got sickincluding yours.

    What was going on? Werent the pool chemicals supposed to be stopping those kinds of things from happening?

    They are, provided that you make sure youre using the right chemicals in the right amounts.

    This scenario unfolds countless times across the United States each day during swimming season. A homeowner takes over the maintenance of their pool, does everything right and ends up experiencing dirt, grime, and sickness after swimming.

    The cause could be a few different things, but one of the most common issues pool service professionals run across is chlorine degradation. Most people dont know this, but when pools are hit by bright sunlight, it can cause most of the chlorine to degrade shockingly fast.

    How fast?

    What can you do to stop this? Add cyanuric acid.
