What is Cyanuric Acid (Stabilizer)?
Cyanuric acid (CYA), also known as stabilizer, is a stabilizing chemical used to help chlorine used in pools to be less affected by sunlight and last longer. Cyanuric acid with the formula 1,3,5-triazine-2,4,6-triol (CNOH) 3 is a chemical compound.
Since cyanuric acid and cyanide are not related, it is suitable for use in swimming pools in terms of health. Cyanuric acid allows the chlorine added to the pool to last longer without being under the influence of sunlight. The most important reason for this is that trichloroisocyanuric acid and di-chlorine, which are in the form of granules, powders or tablets, are the forms of chlorine from which cyanuric acid emerges, which tends to dissolve slowly in water and can last longer in water. What distinguishes cyanuric acid from the others is that the chlorine substance continues to exist in water even though it evaporates into the air after completing its task in water. When it comes to disinfection, the stabilizer takes the leading role. Its use in indoor pools is prohibited. For this reason, it is widely used in open pools in our country.
The function of the stabilizer is to ensure that chlorine stays in the pool water longer and that a more effective oxidation and disinfection process takes place in the pool water. Cyanuric acid should be between 20 - 50 ppm in open pools. Otherwise, the growth of microorganisms such as viruses, bacteria and algae that cause serious diseases in pool water cannot be prevented. If the cyanuric acid balance is not maintained in the pools, you will both risk your health and have a green and dirty pool.
Changes in the level of cyanuric acid in the pool water begin to occur through chlorine in powder or tablet form, which is added to the pool periodically. However, in order to avoid a problem, the stabilizer rate in the pool water should be monitored. When it exceeds the expected limit, chlorine or salt chlorine generators that do not contain stabilizer must be activated. When the cyanuric acid levels in pool water reach 100 parts per million, the pool water gets into serious trouble and the question "How to reduce cyanuric acid?" starts to come into play.
Although cyanuric acid is an important substance in the disinfection work with chlorine, the high concentration of the stabilizer substance over time causes chlorine lock-up, a hazy appearance in the water and gradually increasing chlorine consumption. For this reason, they try to prevent the dispersion of chlorine without being affected by the ultraviolet rays of the sun with cyanuric acid to bond with free chlorine in pool water studies. Excess cyanuric acid, which is used extensively in outdoor pools, begins to eliminate the effectiveness of chlorine in the fight against bacteria in the water.
Cyanuric acid reaching 100 ppm and above in pool water causes an event called chlorine lock-up. After reaching this level, the chlorine thrown into the pool has no meaning. At this stage, the stabilizer in the pool water traps the added chlorine. At such a point, all that needs to be done is to drain most of the pool water and add fresh water to the pool. Thus, the cyanuric acid ratio is brought to normal levels.
The use of cyanuric acid in indoor pools is prohibited. For this reason, it is especially used in open pools. To give examples of pools where cyanuric acid is used:
It is especially suitable for use in newly filled pools or in all pools for a few months a year. The stabilizer (cyanuric acid) added to the pool water should be measured regularly and periodically. Chlorine with cyanuric acid stabilizer stays active as a disinfectant in the added water for a certain period of time. Despite its volatility, it causes accumulation in the added water and can easily exceed the standard values. If you use stabilized chlorine in your pool, it will be useful to have the cyanuric acid level measured periodically once a week. So, how is cyanuric acid measured? Several methods can be used to measure cyanuric acid. The most preferred method is to partially drain the pool and refill it with fresh water. The criterion for this method is that it takes time to determine the extent to which chlorine is locked in. It is sufficient to partially empty the pool and refill it.
In order to reach ideal values in pool water, various chemicals must be added in a certain balance and constantly controlled. Contrary to what is thought when these chemicals are used in pool water, they do not harm human health. In fact, by keeping the required amount, it prevents the destruction of various microorganisms that arise due to use and prevents the spread of elements that threaten human health such as bacteria and viruses. Determining the ideal values for pool water and protecting such chemicals with accurate measurements, the quality of the water should be brought to ideal levels. Thanks to the chemical technology that continues to develop today, water quality is also increased without harming the environment and people. Cyanuric Acid Degree expresses normal values when it is between 20 - 50 ppm in open pools. Cyanuric acid is of great importance for pool maintenance.
Pool water should be tested and analyzed before using pool chemicals. One of the biggest roles in pool water chemicals belongs to the pH value of pool water. If the pH value is below 7.0 ppm, abrasions will occur in the pool joints as it will be acidic. At the same time, pool handrails also melt. This rate, which also negatively affects human health, causes burning in the eyes of swimmers and rashes on their skin. The pH value of pool water is expected to move between 7.2 and 7.6, which are ideal values.
The amount of cyanuric is also an important substance in disinfecting. Always have a table where you can see the amount of chlorine according to the acidity ratio. As the amount of cyanuric acid increases, the effectiveness of chlorine decreases. In order not to be affected by this negativity, you should closely follow the developments with the calculation table. When you need to reduce the cyanuric acid content, it is often sufficient to add water. However, in cases where the cyanuric acid ratio exceeds 100 ppm, a complete change of the pool water is a permanent solution. Pool water becomes cloudy as a result of using more stabilizing chemicals than necessary. What is the importance of using pool maintenance chemicals?
Routine maintenance of pools used every month of the year is mandatory. This maintenance activity, which is mandatory in terms of not harming human health, must be carried out by professionals. . Some damages may occur as a result of maintenance work done by people who do not have knowledge and experience in chemicals. Pool maintenance has a lot of criteria in itself. The type, quantity and quality of chemical maintenance materials are among the main criteria.
WHAT ARE THE THINGS TO CONSIDER IN POOL MAINTENANCE?
While pool maintenance is extremely important for human health, its cleaning requires a special sensitivity. As well as cleaning the water, controlling the pool joints is also important to prevent ceramic spills. In-pool lighting and changes are among the issues to be considered. Pool side gratings should be checked, and if there are worn gratings, they should be replaced to prevent an accident. The pool pump is also one of the issues that are sensitive to maintenance. Pool sand filter control is another item that needs to be done. If deterioration has occurred in the pool filter sands, quartz sands must be replaced. So, how is pool maintenance done?
Precipitant application is made in maintenance works that should be carried out step by step. At this stage, you should first measure the pH value of the water. It is in the range of 6.8-7.2 is a point of attention. After adding the precipitant to the water, keep the system running for at least 4 hours. At the end of the fourth hour, close the pool and let it rest. Take care to use as much as necessary so that the pond is not turbid.
The fastest way to measure cyanuric acid is to test for total chlorine and free chlorine. Free chlorine tests are performed with a test kit. Sample water is taken from the pool where the test will be performed and dpd1 tablet is thrown into the chlorine measurement section. The result is obtained with the melted tablet. In the bound chlorine test, dpd3 tablet is placed in the same section without pouring the sample water from which the result is obtained. After the tablet dissolves, cyanuric acid is determined.
Although the price of cyanuric acid test kits may seem high at first glance, it is much less costly than lost or ineffective chlorine. Those using stabilized chlorine should buy a test kit. On the other hand, those who use non-stabilized chlorine should contact pool professionals. Tests performed by pool professionals take 1-2 minutes and can be done anywhere you want. Since the stabilizer is not depleted, those who use chlorine without stabilizer do not need to measure all the time. It is enough to do it every 3 months. Those who use chlorine with stabilizer should measure at least once a month and keep the value below 80mg/L. When it starts to rise above the specified value, intervention should be taken.
Cyanuric Acid Test Kit is used to measure the amount of stabilizer chlorine in pool water. The kit includes 1 cyanuric acid indicator, 1 test tube, 1 syringe and package insert. It is the most practical measurement tool to measure the amount of cyanuric acid in your water.
The kit to measure the amount of urine and cyanuric acid in the pool is used by following the 4 steps below:
First of all, cyanuric acid should be measured. It should be intervened as soon as it goes beyond ideal levels. "How to reduce cyanuric acid?" Let's examine step by step.
