Where is the chart that shows that Free Chlorine level is required to overcome what ever the CYA level is at?

I heard peole reference this chart but I cannot seem to locate it. I am at FC of 10ppm per the powder and drop test in the TF-Pro Kit and I want to be sure that with a CYA of 60 I am in the correct range.

Thanks

Jeff

Or if you are decent in math just remember that FC should be 7.5% to 10% of CYA.

Awesome, Thanks

so my CYA is 60 I should shoot for a FC of 4.5-6 ? Chart shows target of 7-9?
