I see from the CYA/Chlorine chart that if I had a CYA reading of 70, then I'd want my FC to be at 8 and my shock FC to be 24.
Besides possible skin irritation, what does that high of a CL2 level do to my dyed grey plaster? My pool finish is a combo of quartz and dyed plaster. Will it fade it over time? Any harm to pool equipment or heater?
I am working on getting my CYA down to the 30 - 40 range so I can run lower CL2 levels. But in the meantime.... ?
