Trying to work out a FC issue and hope to search for it .
=======================
I need to update my signature when I get the permission but I have a 15k pool round vinyl above ground. Sand filter with 1.5 Hp Hayward pump. the pool is crystal clear but no FC.
CYA=40
TA=100
PH=7.2
TDS=700
Phosphates=100
TAC=2
FC=0
do I just keep adding bleach until I get FC to stay?
