Because CYA acts as a buffer to chlorine...does that mean that little to zero cya is bad for a liner
as the chlorine is then "more harsh." or is it less harsh to swim wear and skin more than anything else?
I had CYA of 30 just before winter started...I have zero now due to lots of rain and having to
drain down to keep the fill level correct.
Very curious about this since my liner is brand new.
I've ordered more cya to get it back up again.
I keep my chlorine levels always between the recommended 2-6ppm for a cya level of 30
since 30 works best for me (pool mostly shaded)
