@bjsbuds I think you are somewhat confused. Right now your CYA is 30ppm as per your post, your slam level should be FC 12ppm, not FC 24ppm. Do not use the SWG daily targets for your slam level. Slam level is based on CYA only. Reading the article I could see where you would think you need 24ppm, but you do not. Going forward target 12ppm for your slam level.If your CYA is at 30, should your Shock level only be 12?
That is what confused me about the , non SWG and SWG, CYA/FC chart. Don’t mean to confuse, but if CYA is 30 you may be wasting Chlorine.
