The last two times I've tested the CYA - it has been zero. I did think of something just now though - I might need to order new chemicals for the season?
Do I need to add CYA to the pool?
I am using the k-2006 Complete (FAS-DPD chlorine) from Taylor.
Water is slightly cloudy, but a lot of pollen had fallen to the pool bottom and the vacuum stirred it up a little. Ph is 7.4, Chlorine is 4.
It's an above ground, round 33ft and I live in North Alabama.
