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!
