If you own a swimming pool you will need to familiarize yourself with the best way to lower Cyanuric Acid! When Cyanuric Acid (CYA) levels get too high in your swimming pool you will need to lower them. When it comes to keeping your swimming pool looking great, chlorine is one of the most important chemicals in your swimming pool to keep it clear and free of algae but, the most common chemical used to prevent chlorine loss in swimming pools in CYA which is also known as stabilizer/conditioner. During the long, hot summer months the sun’s ultraviolet rays destroy free chlorine but having the proper amount of CYA in the swimming pool can prevent this. That’s why we hope this blog post educates you on why CYA is necessary but also what happens when those levels get too high in your swimming pool (which is extremely common if you use chlorine tablets).

As explained earlier chlorine is extremely important to have in the swimming pool to prevent algae growth but it is also vital to maintain proper pH levels, Total Alkalinity (TA), and Calcium hardness levels if you want to keep your pool looking great and ready to swim in at all times. The bottom line is, if CYA is used properly it can reduce the cost of maintaining a swimming pool because it prevents chlorine loss and reduces the amount of chlorine needed to properly sanitize a swimming pool.

When it comes to proper amounts of CYA most pool professionals will tell you that the ideal amount of CYA is between 30-50 parts per million (ppm) but depending on how much direct sunlight the swimming pool gets or if you have a salt system, that number might need to be a little higher. Whereas, when the CYA levels rise above 100ppm, that can cause a fair amount of other problems too. The biggest issue when CYA levels rise above 100ppm is the effectiveness of chlorine because the higher levels tend to bind up the chlorine making it harder to kill algae and other bacteria. When this happens the only way to lower CYA is to replace the water in the swimming pool which can be done by a drain and refill or using our Reverse Osmosis (RO) mobile filtration system. Just this past week we a 23,500-gallon swimming salt pool because their Calcium Hardness (CH) and CYA levels were high. When we showed up onsite and measured water chemistry this is what we found:

Calcium Hardness – 670ppm (high for their salt system)

Total Dissolved Solids – 4217ppm

Cyanuric Acid – 120ppm (high for their salt system)

After filtering their swimming pool for 15 hours we were able to leave them with the following ending chemistry:

Calcium Hardness – 120ppm

Total Dissolved Solids – 919ppm

Cyanuric Acid – 35ppm

With numbers like these, their swimming pool not only looks great but their salt water chlorinator is working much better too! If you should have any questions about how this service works, please contact us today!

    There are few isotopes of chlorine. The most common isotopes are Chlorine-35 and chlorine-37. However, chlorine-35 is the most abundant isotope among these two due to its high stability. The most stable oxidation state of chlorine is -1. By obtaining one electron from outside (from an electron donating chemical species), chlorine atom can get a stable electron configuration by completing the electron configuration. Chlorine gas and most other chlorine-containing compounds can kill bacteria. Hence, it is used as a disinfectant to treat drinking water and swimming pool water. However, chlorine gas is mainly used in the production of PVC (polyvinyl chloride).

    Rather than adding chlorine, rapid flows of freshly extracted geothermal water in the baths will ensure that the water is always clean.

    Dichloroisocyanuric Acid DiChlor Click for more DiChlor is most commonly used in dissolvable tablets. It has an almost neutral effect on ph and so is great to use in situations where ph is significantly drifting. DiChlor is also stabilised which means that it will add sunblock to the water and prevent chlorine loss (however Sunblock levels do need to be carefully monitored). Tablets will not quickly raise the chlorine level but rather slowly dissolve and maintain a chlorine level with additional shock doses of granular or liquid chlorine added to the pool when needed.

    Funny how no one knew about this secret meeting until Susan Rice wrote herself a CYA email. Hahaha, liars always have difficulty remembering lies, let alone remembering friends lies! The more that they fight to keep this information secretive, the more we the people need to know what klandine tricks they were up to.
