Hello everyone this is my second season with my pool and the first season opening by myself to try and save some money. I am using my Taylor k-2006 kit and replacing the Reagents that are expired or expiring soon. I am waiting till tomorrow for my r0871 reagent to come in to “accurately” test my fc and cc but my question would be is it possible to have “chlorine lock” with 30ppm of cya, the issue I’m having is that it seems that I have higher cc than fc. Any help would be appreciated, thank you for your time
