I have been very interested on CYA and Chlorine relationship since reading on forums about it posted on here. Through my readings I have begun to see that it can be your best friend and can also be your worse nightmare in pool water if allowed to get out of hand. I am not sure if anyone has read this article that has a lot more knowledge in this topic than I, but thought I'd share it. It's called ("Cyanurics ~Benefactor or bomb?"
by Kent Williams, Executive Director of the Professional Pool Operators of America.) Here is the link http://www.ppoa.org/pdfs/PrP_Cyanuri...0or%20Bomb.pdf
One of the things I got out of the article was that a need of 5 to 10 ppm of CYA is all is needed to achieve the needed protection from ultraviolet rays. I also concluded that even at a level of 70 ppm CYA, UV protection is generally the same as if it were at the 5 to 10 ppm level. But with increase in CYA above 70 or so ppm comes a big drop in the effective use of residual chlorine that is in the swimming pool. If I have misinterpreted this information, I am all ears to hear from the experts. I trust the expert advice of you guys here. Just thought this was a very good article and would love to get some input from others. This topic is very interesting to me and could possibly help save some money in the long run.
Thanks and hope this the proper forum for this site,
