How to raise cyanuric acid levels in a pool

Cyanuric acid – What is it exactly? It is actually a pool chemical that forms a temporary bond with your swimming pool chlorine. It works to protect your pool’s free chlorine from being destroyed by the natural UV rays of the sun. This particular pool chemical is a necessary ingredient to your water chemistry if you are using unstabilized chlorine  as a water sanitizer or disinfectant in your pools.

Without it your free chlorine residual will be loss in less than an two hours- this is because chlorine is very susceptible to the ultraviolet rays of the sun.

As result of this process, your chlorine residual can drop well below the recommended level for swimming pools.

This creates a very dangerous environment for pool bathers because diseases can be transmitted very easily between individuals. When cyanuric acid is present in your swimming pool water in sufficient amount – the free chlorine residuals will remain in the water much longer. This could be up to three to ten times longer than if  cyanuric acid (CyA) was not present.

In case you are wondering – cyanuric acid does not have any disinfecting properties. Therefore it cannot be used as a swimming pool or spa sanitizer. CyA is a pool chemical that can only be used as a stabilizer for pool chlorine. It is not a stabilizer for bromine either.

If you use the CyA conditioner or stabilizer in your swimming pools, it has to be maintained between 30 to 50 ppm. This is the recommended level that will cause your swimming pool chlorine residual to have optimum effect in your pool water. Thus giving your pool chlorine optimum protection from the sun’s ultraviolet light.

When Should You Use Cyanuric Acid?

Basically cyanuric acid is added to your pool water as needed. This is normally when it is very difficult for you to get or maintain a free chlorine residual of 2 – 3 ppm in your swimming pools. You should perform a cyanuric acid test (CyA test) acid test at least once a month; however, if you are using stabilized chlorine to treat your pool water, then you will need to do a cyanuric acid test every week.

When Should You Add Cyanuric To Your Swimming Pool?

When you are adding Cyanuric Acid to your pool, it will require regular testing of this chemical as I mentioned earlier. The reason for this is that we do not want the level of this pool stabilizing chemical to reach its maximum in your pool water. Because if it does, it will render your pool chlorine ineffective.

Now there are a couple of ways that you can add this chlorine stabilizer to your pool water!  One way is to have the pool chlorine stabilizer suspended in perforated plastic container and add it to the pool. Another way is to dump it into a surge or atmospheric tank. This allows for the dissolution of the chemical without you having to close your pool facility.

Cyanuric acid can also be added directly to the swimming pool but doing it this may delay the opening of your pool.

If you manage or run a big commercial pool at a resort or water park, you do not want to have delays.

This is a very big deal when it comes to blowing away your guests and keeping them happy.

If you broadcast Cyanuric acid (CyA) directly in your pool, opening delays are caused by the sight of the pool chemical at the bottom of your swimming pool.

You see – depending on the size of the granules of the cyanuric acid, it can take as long as 48 hours for it to be completely dissolve into full solution. For this reason, using a surge or atmospheric tank is the best option to use.

Lowering Cyanuric Acid In Swimming Pools

It is a known fact, that if you are using cyanuric acid (CyA) in your swimming pools, you do not get rid of it. This is another reason why you should constantly test its level and maintain it between 30 and 50 ppm. You see, as you add this chlorine stabilizer to the water of your swimming pool, it increases over time.

Keep in mind that the recommended maximum ppm level of this pool chlorine stabilizer in swimming pools is 100.

Once it gets too high, you will have to get rid of or lower it immediately. The question is how? There is no known pool chemical that will lower or eliminate it. The only way to get rid of the cyanuric acid in a swimming pool is to drain your pool partially or completely.

In most cases it is best to drain the pool completely and re-balance your pool water chemistry over. When you refill your pool, you will have to begin adding CyA once again. This is only necessary if you are indeed using unstabilized chlorine as your main source of chlorine disinfectant.

Again high levels of  Cyanuric Acid (CyA) is not good because it can also lead to an increase risk of algae growth. It also reduces the effectiveness of your pool chlorine at very high levels. This is because at very higher levels, the amount of time required to kill bacteria in the water is increased. This is not a very healthy pool environment for your pool swimmers.

Beside health related problems, other swimming pool problems such as increased cloudiness (cloudy pool water) and high combined chlorine levels can occur as well.

Where Not To Use Cyanuric Acid

This chlorine stabilizer should not be used in water of indoor pools. Remember that CyA is used to reduce or limit the loss of free chlorine caused by sunlight; therefore, using it in the water of an indoor pool has zero benefit. You should also not use any other pool chlorine such as Trichlor or Dichlor which already contains Cyanuric acid in them CyA either.

How Much Cyanuric Acid Is Too Much?

As I mentioned earlier, when the Cyanuric acid CyA level in your pool reaches 100 ppm – it has to be lowered. This is the max level that was set by The Nebraska Swimming Pool Act. And according to a study done by The Center For Disease Control (CDC), CyA significantly reduces chlorine’s ability to inactivate Cryptosporidium.

And as we know, this disease is very resistive to swimming pool  chlorine – so just imagine how rampant it will be in a pool that has no free chlorine disinfectant present to combat it.

Because of the findings of this study done by the CDC, the Lincoln Lancaster County Health Department recommends that swimming pools should not exceed a level of 30 ppm when using cyanuric acid.

What causes high cyanuric acid in pools? Maybe you already know, but pools contain lots of chemicals to keep them healthy.

Pools are more than just bodies of pristine water to be enjoyed in the warmth of the summer months; they are made of chemical solutions designed to keep you and your loved ones safe when basking in their embrace.

What are Some Common Pool Chemicals?

Aside from the question,”what causes high cyanuric acid in pools?” it is also important to identify the common chemicals present in most pools. Chlorine is the most common chemical found in pools. Its purpose is clear: To disinfect the pool of any harmful substances. Chlorine is a chemical “cleaner” that rids the water of pathogens that could negatively affect humans and their health.

Often found as a compounded chemical as calcium hypochlorite in solid form or sodium hypochlorite in liquid form, chlorine creates chemicals as an offspring when combined together with the water.

The main chemical that is created by the mixture of water and chlorine is hypochlorous acid. The hypochlorous acid then does the “dirty work” in taking care of the water by killing bacteria, eradicating pathogens, and oxidizing the water itself.

What are Stabilizing Agents?

Frequently included in the chlorine content utilized to clean the pool are stabilizing agents. These are used to protect the chlorine from breaking down prematurely when exposed to ultraviolet light, thus improving the effectiveness of the chlorine itself, allowing it to care for the pool water as best as possible.

Cyanuric acid is a common example of a stabilizing agent.

How do I Use Cyanuric Acid Safely?

Once pool owners learn of the plethora of chemicals in their pools, one of the common questions we get (that you might have as well) relates to the proper use of cyanuric acid.

As a general rule, you should maintain an amount of 60 to 80 parts per million (ppm) of cyanuric acid in your pool if your pool is exposed to great amounts of sunlight. Maintaining this range will allow your pool to remain in a state of optimal health, avoiding too little or too much of the chemical which could have harmful results on either end.

If you have an indoor pool, it is generally thought that your pool does not need cyanuric acid as exposure to sunlight in indoor pools is at a minimum.

However, if your indoor pool does receive periodic to frequent sunlight exposure, then cyanuric acid should be added as needed to safely protect yourself, the pool structure, and the water.

In this case, it would be best to consult a pool technician to learn what amount of cyanuric acid would be best for your water.

If your pool uses Oxidation Reduction Potential in its system mechanisms, then a cyanuric acid range between 30 and 50 parts per million (ppm) should be strived for.

What Causes High Cyanuric Acid Amounts?

High cyanuric acid amounts in your pool are likely caused simply by applying too much of the chemical into the pool itself.

Often, miscalculations in measurement, misunderstandings of proper amounts needed, or simple human errors are the factors that can influence increased amounts.

If you have any hesitations when it comes to adding chlorine and cyanuric acid to your pool, I would best recommend that you consult with a pool technician before you begin.

When it comes to chemicals and the safety of your water and your loved ones, you can never be too safe.

What Does Too Much Cyanuric Acid Look Like?

The nice thing is that the signs are pretty obvious if your pool has too much cyanuric acid. You will be able to see changes in the water structure which will ward you with caution.

One of the main concerns you would likely see is a decrease in the transparency of the water, meaning it would begin to appear more foggy and cloudy than it naturally or typically would.

If you notice this change in your pool, you would be wise to take swift action to resolve the issue before it increases in intensity.

The second change in your pool that might not be as clear to see (pun intended) is the effectiveness of the cyanuric acid itself. As more and more cyanuric acid is present, it begins to become less effective as a whole, thus limiting the power it has to properly do its job as required.

How Do I Fix My Water if I Have Too Much Cyanuric Acid?

There is a simple fix to solve these issues: Simply replace some of the overly-saturated and cloudy water with fresh water.

This replacement will allow the high levels of cyanuric acid to decrease while increasing the clarity of the water, bringing it back to a healthy state as a whole.

This is the most simple and cost-effective solution to the issue. However, in doing so, just be sure to dispose of the discarded water properly to ensure safe protection of the environment from harm.

This product will further assist you in clearing up the cloudiness of your pool to help it become the best it can be.

With these simple tips, you can care for your pool to your very best bringing your pool itself to its very best. By taking proper care of your pool, you will be able to provide fun and entertainment for your family, friends, and loved ones for many years to come!

How to raise cyanuric acid levels in a pool

How to raise cyanuric acid in pool is the most requested question I get from the pool owner. So, I decided to write down the complete guide on it. Hopefully, you’ll get all the answers you need.

Cyanuric acid helps the chlorine to work more effectively in your pool, but if your cyanuric acid levels get too high or too low, you could end up weakening your chlorine and causing everything from algae to cloudy water.

Here are a few simple steps that you can take to keep your cyanuric acid levels balanced in your pool.

what is cyanuric acid?

Cyanuric acid is also known as CYA, Pool Conditioner, or Pool Stabilizer. It comes in both liquid and granular forms.

You can even get it premixed in with chlorine tablets or sticks. These products are called stabilized chlorine.

Cyanuric acid allows your pool water molecules to hold on to the chlorine, specifically free chlorine.

Now, free chlorine is the amount of sanitizer that’s available to clean your pool water. The other good thing about cyanuric acid is that it has little effect on alkalinity, pH, and calcium hardness level.

how does cyanuric acid help stabilize chlorine?

Well, when you add chlorine to your pool water, it transforms into a sodium hypochlorite ion. When UV rays from the sun hit those ions, they break apart and the chlorine evaporates, leaving very little free chlorine in your pool water.

Cyanuric acid binds those ions. It prevents them from breaking apart when exposed to UV rays.

  • if your cyanuric acid levels are too low, your pool won’t hold on to the chlorine.
  • If your cyanuric acid levels are too high, your water will become saturated and it won’t hold on to more chlorine.

The right balance between cyanuric acid and free chlorine levels will help you get the most
out of your sanitizer.

What are the right cyanuric acid levels?

I recommend keeping your cyanuric acid levels between 30 and 50 parts per million.

If your cyanuric acid level is over 50 parts per million, it can inhibit your chlorine. You may notice algae growth, difficulty maintaining balance chemistry, cloudy pool water, and decreased sanitizing.

  • if the levels climb above 100 parts per million, you may not be able to even read that exact amount on a test strip. You’ll want to take that sample into your local pool supplies store for more accurate testing.
  • if your cyanuric acid gets low, between 0 and 30 parts per million, you’ll need to add some to your pool.

You’ll also want to know your free chlorine levels.

Your free chlorine should be between 1 and 3 parts per million.

When using cyanuric acid, aim to keep your chlorine levels at about 7.5% of cyanuric acid levels.

That means if your pool has 50 parts per million of cyanuric acid, you’ll need to keep three chlorine at 3 parts per million to effectively sanitize your water and prevent issues like algae.

When should you test your cyanuric acid levels?

Well, besides regularly testing your pool water, you’ll want to test your water at the beginning and the end of pool season.

If your cyanuric acid is low at the beginning of the season, you’ll end up using more chlorine in the month ahead.

And if it’s high at the end of the season, it might be time to change your pool water.

Secondly, test your pool water right after a major rainstorm. Diluted water can also result in lower cyanuric acid levels.

Finally, if you notice the strong chlorine smell on your pool, that can be a sign that there’s actually too much cyanuric acid affecting your chlorine.

So, check your chlorine and your cyanuric acid levels.

how to lower the cyanuric acid levels in your pool?

If your cyanuric acid levels are too high, check to see if you’re using stabilized chlorine.

Remember, stabilized chlorine already contains a small amount of cyanuric acid. And if you see the following chemicals listed on your label, your chlorine contains cyanuric acid.

If this is the case, you may want to switch to chlorine without the added CYA to prevent your levels from rising again.

Unfortunately, diluting your pool water is the only way to lower high cyanuric acid levels.

So, drain a little water from your pool to bring down the water level, and then top off your pool with fresh water.

Now, if the levels are extremely high, you may want to completely drain your pool and refill it with fresh water. This is rare, and stabilized chlorine with CYA can hang around in your filtration system, so you may want to backwash or change your filter.

Cyanuric acid has also been found in pool plaster and in calcium scales. So if your levels climb rapidly after you refill your pool, that lingering CYA could be the problem.

How to raise cyanuric acid levels in your pool?

Now to increase cyanuric acid in your pool. You just simply need to add it.

Remember, CYA is an acid.

It can damage your filter and pool, especially if you have a vinyl liner.

Always read the manufacturer’s instructions before using it, but here’s the way that we recommend adding it to your pool.

You’re going to need cyanuric acid, a five-gallon bucket, safety goggles, and acid-resistant gloves, and warm water.

First, you want to fill the bucket at least halfway with warm water, put on your gloves and your goggles, and add a dose of cyanuric acid to the bucket.

Check the product instructions for your pool size.

As a general rule for a 10,000-gallon pool, you’re going to need to add 13 ounces of cyanuric acid to increase your CYA by 10 parts per million.

Pour the contents of the buckets directly into your skimmer, and then run your pump
for at least a few hours to stir in the solution to your pool.

That’s everything that you need to know about balancing cyanuric acid levels in your 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. You can’t have a safe-to-use swimming pool when you don’t maintain those chemicals at a balanced level.

The balance level of pool chemicals is not only good for you but also for the pool itself. For instance, 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’s surface.

So, what is actually cyanuric acid? From its name, of course, you can simply guess that it’s some kind of chemical, but how does it work to maintain your pool water? In short, cyanuric acid is chlorine’s best friend which works to stabilize the level of free chlorine.

Free chlorine – which is a type of chlorine that actually works to sanitize pool water – can get reduced when it’s exposed to sunlight. That is the time when you need cyanuric acid to help you before some problems caused by bacteria and even algae happen due to low free chlorine levels.

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. Find out how to raise cyanuric acid in pool in a simple tutorial below.

How to Raise Cyanuric Acid in Pool Tutorial

Take a very careful measure when you are sure that you have to raise the cyanuric acid in your pool water. If you add too much, you can cause the high cyanuric acid level which will make you have to solve a more complicated case.

Test the Water

To find out the level of cyanuric acid in your swimming pool, you have to test the level of the chemicals of the water. The ideal range of cyanuric acid is around 30 ppm to 50 ppm, so when it’s lower than 30 ppm, that’s the time when you need to raise the level.

Use a water tester strip or kit to check the level of cyanuric acid. If you want to get a more accurate result, you can use a water tester kit though the process may be more complicated.

Add Cyanuric Acid

When you are sure that the level of cyanuric acid is lower than the ideal range, you can add more cyanuric acid. Cyanuric acid – which is produced separately from chlorine – is commonly sold in granule or liquid form. The rule of thumb is 4 lbs of cyanuric acid can raise 30 ppm of 10,000 gallons of water.

  • Bucket
  • Wood bar
  • Rubber gloves and other protective gear like a dust mask, eye goggles, and long-sleeved shirt if necessary.
  • Calculate the amount of the cyanuric acid that you need to use by measuring the level of the cyanuric acid of the water and the volume of your pool or you can use some websites that provide the feature to calculate the pool chemicals like poolcalculator.com.
  • Add the cyanuric acid to the bucket and mix it with water. Follow the manufacturer’s instructions to find out the amount of water that you need.
  • Stir the mixture with a wood bar for a safer way since it may irritate your skin.
  • Pour the mixture around the perimeter of your swimming pool evenly.

Run the Pump

To evenly mix the water with cyanuric acid, you need to run the pump of your swimming pool. You need to keep it running for several hours.

Well, that is the simple tutorial on how to raise cyanuric acid in pool that you can follow easily. Different manufacturers usually give different instructions, so you need to read the label before starting the process.

Rising the level of cyanuric acid when it’s below the ideal range should be done carefully since rising it above the recommended level can cause high cyanuric acid. To correct it, you need to partially drain the pool and add fresh water to it. So, always keep the level in a balanced range.

Well, have a nice try on stabilizing the level of the cyanuric acid of your swimming pool!

How to raise cyanuric acid levels in a pool

Test strips are the easiest way to test cyanuric acid. Cyanuric acid is raised by adding chlorine stabilizer containing cyanuric acid. The only way to lower cyanuric acid is by replacing water.

How to Test Cyanuric Acid

Unlike free chlorine, cyanuric acid levels should remain level day-to-day. An exception might be if there is a heavy rain storm through which your pool is left uncovered. The rain will introduce a substantial amount of fresh water to your pool, which may dilute the concentration of cyanuric acid. You should always test your pool’s chemistry after such an event.
Test strips are the easiest way to test cyanuric acid. It’s important to get test strips to that include a test for cyanuric acid, especially if you have a hot tub. To learn more about why it’s important to keep cyanuric acid levels low in hot tubs, check out What is the Right Cyanuric Acid Level for Swimming Pools and Hot Tubs?

To test your cyanuric acid levels with a test strip, follow the instructions on the test strip case. Typically, you will need to submerge the strip in your pool for a minimum number of seconds. Then, you will need to wait some time for the water to react with the reagents on the strip. Finally, you will compare the color of the cyanuric acid test on the strip with the range of colors on the test strip package to get an estimate of the amount of cyanuric acid in your pool.

You may use a test kit to test your free chlorine and pH levels. The test kit may come with a cyanuric test as well. However, cyanuric acid is less critical to measure exactly than free chlorine or pH. It also does not need to be tested as often. Once per week is plenty. Therefore, test strips should suffice for most every need of pool owners and pool professionals alike

How to Raise Cyanuric Acid

Cyanuric acid levels are raised by adding pool stabilizer. It’s called stabilizer because cyanuric acid stabilizes free chlorine from being evaporated by the sun. For more information, check out The Relationship Between Swimming Pool Chlorine and Cyanuric Acid.

Many chlorine products come with stabilizer already mixed in. Adding a chlorine solution with stabilizer will automatically raise your cyanuric acid levels. However, liquid and granular stabilizer solutions may be purchased and added separately

How to Lower Cyanuric Acid

The only practical way to lower cyanuric acid is by replacing some of your existing water with fresh water. To calculate how much water should be replaced, subtract the desired concentration of cyanuric acid from the current concentration and divide the difference by the current concentration.

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, it’s chlorine’s 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 to Raise Cyanuric Acid in a Swimming Pool

Tools and supplies you need to prepare:

  1. Water tester strip or kit
  2. Bucket
  3. Wood bar
  4. Protective gear (rubber gloves, goggles, etc.)

Please make sure that you take a careful measure of raising the cyanuric acid because if you add too much, you can cause a high cyanuric acid level which will make you have to solve a more complicated case.

#1 Test the Water

  • First, test the level of the chemicals in the water to know your water chemical level.
  • The ideal range of cyanuric acid is around 30 ppm to 50 ppm, so when it’s lower than 30 ppm, you need to raise the level.

Are you adding more and more chlorine to your pool with diminishing results?

You go out to your pool every day, test it for the proper chlorine levels, and add chlorine tablets or other liquid chlorine products to keep the levels between 1 – 3ppm — but you are still facing problems with algae, murky water, and chlorine effectiveness. What most pool owners don’t know is that cyanuric acid is added to chlorine treatments to help keep it from evaporating. Eventually, though, chlorine is consumed by the sanitation process and the levels drop. Unlike chlorine, cyanuric acid does not degrade and continues building up.

How to raise cyanuric acid levels in a pool

Always more maintenance

What is Cyanuric Acid

Cyanuric acid is used in outdoor swimming pools to stop chlorine from rapidly evaporating in the sun. With help from cyanuric acid, pools don’t have to be managed daily. Instead, homeowners and service professionals can manage pools less often and with less effort.

Here’s the problem:

The amount of cyanuric acid in your pool greatly affects the disinfection, oxidation, and algae inhibition rates of the chlorine. Studies and research show that ORP levels drop with the introduction of more cyanuric acid (indicating that the chlorine is lowering in effectiveness). High levels of this chemical will also damage pool plaster surfaces and even become ineffective against the growth of a dangerous microorganism called Cryptosporidium parvum (a chlorine resistant organism known to cause gastrointestinal illness).

Due to the fact that cyanuric acid does not evaporate or degrade, the levels continually build up and overtime pool owners are forced to drain their pool.

The Relationship of pH, Chlorine, and Cyanuric Acid Levels

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 chlorine’s diminished ability to kill bacteria and viruses. In Florida, the Department of Health states that a pool’s 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.

Problems Beyond The Pool

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

  • The drain and refill solution is no longer a sustainable option in areas where drought conditions are a problem. For pool owners in a state such as California, Texas, New Mexico, Nevada, Georgia, or Arizona — this solution is falling under increased scrutiny due to water shortages and the need to improve use of limited water resources. In Arizona, if you are caught illegally dumping pool water — you could be fined up to $15,000.
  • The ineffective management of pool drainage introduces toxins to the environment. Depending on the state and county — disposing the waste from draining your pool will fall under a different set of regulations. Even so, there is always a burden to the environment when disposing of swimming pool waste. This discharge can contribute toxic and carcinogenic materials to fish and other wildlife. Introduction of chlorine can cause damage to trees and harm surrounding forests or parks.

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

Draining Your Pool Is a Distant Memory

In 2015, a revolutionary product was introduced to the pool industry. It is called Cyanuric Acid Reducer. Bio-Active Products Inc developed this outstanding product in partnership with BiOWiSH Technologies.

What Should Cyanuric Acid Levels Be in Pools?

The two most important factors to consider in terms of balancing your cyanuric acid levels are whether your pool uses a salt water generator and how much direct sunlight your pool receives. We will discuss the former in the next section, so feel free to skip ahead if you use a salt water generator to sanitize your pool.
The energy contained in UV light from the sun causes the hypochlorous acid and hypochlorite ions formed from the reaction of chlorine and water to break apart in a process called photolysis. Learn more in our article What is Cyanuric Acid?
If your pool receives more direct sunlight, more free chlorine will be lost due to photolysis. One way to combat this is by adding more chlorine, more frequently. However, that is both expensive and time consuming. A better approach is to keep your cyanuric acid levels slightly elevated between 60 and 80 ppm. This also means will want to keep your free chlorine levels elevated between 4 and 5 ppm.

What Should Cyanuric Acid Levels Be with a salt water swimming pool?

Saltwater pool manufacturers recommend maintaining cyanuric acid levels around 60-80 ppm. This is a bit higher than the 30-50 ppm range recommended for non-saltwater pools. And if you live in an area where your pool gets a lot of direct sunlight, you may even consider bumping your cyanuric acid up to 80-100 ppm.
The reason saltwater pools demand elevated cyanuric acid levels has to do with the output of the salt cells, themselves. With a saltwater pool, you are not adding chlorine directly. You are adding salt which gets processed into chlorine via a saltwater [chlorine] generator.
You may recall that salt is sodium hypochlorite. Remember that hypochlorite undergoes photolysis from UV light. So, saltwater pools are effectively taxed double by sunlight. First, when the salt is added to the pool. Second, after chlorine is generated from the salt. That is why saltwater pools demand a higher cyanuric acid level between 60 and 80 ppm.

Hi all – I also have a CYA question. My pool has been up for a week and it’s looking good! I got my test kit from TFP and the first time I tested the CYA, it registered <20, CL - 1
pH – 7.4
CYA – <20

What is the best way to raise the CYA?

So tonight I checked the water :
FC .5 – added bleach as per The Pool Calc
pH 7.2 – added borax as per The PC 30 mins after the bleach
CYA – <10 - I have some Aqua Chem Shock Plus Stabilizer

So how long do I wait to add the Shock Plus per PC ?

CYA Cyanuric Acid (Read pool school!!) sold at wal-mart as Stabilizer or conidtioner.

use pool calculator to calculate dosage for your pool. Do the dosage in steps to ensure you don’t unintentionally get a higher CYA than you want. CYA can take a week to fully dissolve so don’t rush to add more if you think the test is still low (highly subjective test for CYA) Once you have too much the only way to get rid of it is Water replacement

Read Pool School thru the link at teh top of the screen!

old sock, rubber band, tie off to ladder. Then come by every couple hours and squish the sock and let the softened powder disperse. Use the pool calculator to determine how much stabilizer will add 20ppm of CYA to your pool. That should get you up to about 30ppm which is low for super hot climates but also a good starting point until you can get an accurate reading for CYA. Then, assume you have 30ppm CYA in the pool and set the pool calculator for that number. Remember, adding CYA will change your target, minimum and shock levels to min 2, target 6, shock 13 whereas without CYA you’re looking at 1, 3, and 10.

Run your pump full time. It won’t burn up, it has water in it. With these small pools and inefficient pumps, filtering is very important. I actually run two Intex/seasonal pool type pumps on mine. Full time. They are both 1000gph pumps. One sucks at the bottom of the pool, one is on the skimmer. Works for me till I decide to invest in a better pump/filter.

Yup, powdered stabilizer in the sock. I use triclor tabs to add CYA when I do my monthly “store test” since my kit doesnt test CYA, in fact just store tested today.

A month ago the CYA was 30, now it is 25. I’ll pack my type A/C filter with 1 inch tabs two/three times, then switch back to bleach when I see the FC drop..

CYA is an important test, but only gets critical when it is too high or too low. Too high binds your chlorine causing needs to keep a higher chlorine ppm. Too low, your chlorine burns off in the sunlight and doesnt kill the green meanies.

As far as I’m concerned, with these Intex pools daily use is preferred and constant pumping are mandatory due to the lethargic flow.
