Hi, 

I have been using diclor in my pool for the last year and have just used a load of it to shock my pool. Until now, I didn't realize it had CYA in it. Now I'm worried that my CYA levels are through the roof and I have been reading that this could make my chlorine ineffective. I can't get hold of a CYA test kit at the moment as the shops are all closed due to the pandemic. Until I can get hold of one, I'll use unstablized chlorine. My question is: if my CYA levels are too high, how do I know if my chlorine is effective? Is it possible to have a FC reading but that chlorine still not be effective at killing germs?

thanks

The free chlorine becomes less effective with higher CYA levels. Unless your CYA level is way above 100 ppm, you probably won't have an issue if your keep your FC between 2-4ppm.
