I totally understand the relationship of cya and free chlorine. My pool has been sparkling for two years now all due to this site. However, I have a question. When people seek help from this site, their cya levels are usually way high - like over 100. With levels like that you need to have very high chlorine levels to slam and then moderately high levels to keep clear.
Here is something I never fully understood... Is a chlorine level ever too high and unsafe to swim in IF it is within range for your cya? For example, with a cya of 110 you need between and 8-13 ppm of chlorine to stay clear- I get that - but is swimming in a pool with that much chlorine ever dangerous? Does the cya have some kind of buffering affect where it is not as potent? So is an 8 chlorine with a cya level of 110 the same concentration of a 3 chlorine level with a cya of 30?
Thank you!
