My pool is crystal clear but noticed I've had to add more chlorine lately. I tested today and here are my readings.
FC=0
CC=0
TC=0
PH=8+ Maybe like 8.2
TA=140
CYA= I filled it to the very top of tube and the dot disappeared. So like 20-25?
What should I add/adjust first and what/ where do I get the stuff to raise CYA?
