I've been reading up on CYA/chlorine relationships. Some of ChemGeeks works and some of the papers he recommends. I understand the basic ideas of what's going on but I'm still confused why high levels of FC are less harmful in the presence of CYA. I'm really struggling to accept the premise of this forum that such high levels of FC are fine. It's a constant pounding, the cry of conventional pool experts, that FC should be between 1 - 3 ppm and swimming should not be allowed when it is above 5 ppm. I keep getting ready to raise my levels but then I get squeamish again and adjust my water to be no higher than 4 ppm. At my level of CYA, I should keep FC levels between 3 - 7 ppm and a target of 5, but I'm afraid.
Please explain (in layman's terms) why the belief is so different here. Does CYA actually make chlorine less potent? Less of an oxidizer? Why has conventional wisdom not caught up? I don't see how their views help profits any? There is much experience here of pools having FC levels above 5 and there is no harmful effects?
Thanks for all your time,
Ed
