CYA is a friend when used with the correct ratio to free chlorine Benefits to Using CYA in Pool Water Benefit one is the UV protection Benefit two is the flattened pH dependency With CYA 30, the HOCl concentration drops by 15% between pH 7 5 and 8 0 Benefit three is the chlorine reservoir All that "useless" chlorine bound to CYA stays in
- CYA - Cyanuric Acid Test - Trouble Free Pool
If your CYA level is 90 or higher, repeat the test but adjust the procedure as follows: Fill the CYA mixing bottle to the lower mark with pool water Continue filling the CYA mixing bottle to the upper mark with tap water Cap the bottle and mix for 30 seconds Pour off half of the contents of the mixing bottle, so it is again filled to the
- How did the CYA levels get so high in my pool - Trouble Free Pool
CYA increases over time in a pool if you are using stabilized chlorine products, Trichlor pucks tabs (or powdered "shock") or Dichlor granular (sometimes also sold as "shock") For every 10 ppm Free Chlorine (FC) added by Trichlor, it also increases Cyanuric Acid (CYA) by 6 ppm For every 10 ppm FC added by Dichlor, it also increases CYA by 9 ppm
- CYA Chlorine Relationship - Further Reading - Trouble Free Pool
What is the Relationship of CYA with Free Chlorine in a Pool? The most important quote from the Aqua Magazine article is: With a CYA:FC ratio of 20:1, the concentration of HOCl stays pretty constant at 0 02 ppm The crucial factor in understanding chlorine safety is the CYA:FC ratio
- 3 chlorine tabs without CYA - Trouble Free Pool
The problem with this slow dissolving form of chlorine is that it will cause CYA levels to rise since once the chlorine is used up the CYA remains The next slowest dissolving form of chlorine is calcium hypochlorite (cal hypo) which does not contain CYA but will cause calcium levels to rise over time
- The Free Chlorine and Cyanuric Acid Relationship
Maintaining proper levels of FC according to CYA keeps your water safe and clear without using ineffective, expensive chemicals like algaecides The pool, equipment, and people are safe with FC levels up to and including SLAM level FC for your CYA CYA typically degrades 5-10PPM in the summer, so ensure you test and replace CYA at least monthly

It can provide CYA measurements at 5, 10, and 15 ppm that the standard CYA tests cannot It also contains a dilution vial to dilute the sample 5 to 1 and test CYA from 100 to 500 ppm by dilution Measuring low levels of CYA can be useful for hot tubs that use it to buffer the chlorine harshness
- Adding CYA - Correct Method? - Trouble Free Pool
CYA is acidic when it dissolves into water and so it is not a good idea to leave the sock in the skimmer without the pump running Pouring granular CYA into the pool directly, or into the skimmer as recommended on stabilizer bottles, is not recommended as it takes a long time to dissolve and the granules can sit against the pool surface
