The Free Chlorine and Cyanuric Acid Relationship
2024年7月20日 · Stabilizer or cyanuric acid (CYA) protects your free chlorine (FC) from the sun. With no CYA stabilizer in your pool, FC will be quickly consumed by sun exposure instead of doing its job to oxidize organic material like bacteria and algae. If your FC level drops too low in your pool, you risk allowing algae to grow.
Chlorine/CYA Chart - Trouble Free Pool
2019年1月20日 · chem geek. Three reasons. 1) Without any CYA then chlorine breaks down very quickly in sunlight -- cut in half every 30 minutes in noontime sun. 2) Without any CYA you are overdosing your pool with chlorine because you can't really control a small 0.1 ppm of Free Chlorine (FC) in your pool.

CyA.. How Much, How Often to Add, Typically? - Trouble Free Pool
Rockville, MD. Apr 10, 2017. #3. Your entire pool needs 11 lbs to go from 0-80ppm (high end of suggested with a SWG). You only need to add cya as water is added. I would think a single 7lb packet would last you a while as long as it is for maintaining CYA level.
How did the CYA levels get so high in my pool - Trouble Free Pool
2012年6月29日 · 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 ...
How to add CYA? - Trouble Free Pool
2014年4月5日 · Copperhead said: Just added 8 lbs. this way and it was gone in an hour. You have in-floor cleaners, which keep the acid from sitting on the floor. However, most people do not have in-floor cleaners. In any case, I don't think that broadcasting cyanuric acid is a good method.
CYA - Trouble Free Pool
2022年7月7日 · You will have to maintain higher FC levels (way higher than SLAM equivalent) to have enough buffer. By industry standards these higher levels of up to 4, 5 or even 10ppm (with no CYA, these levels are insane, with CYA they would be completely acceptable depending on the exact CYA level - it's all relative) are what you often find in public pools.
