After spending a fortune last year at the pool store a friend recommended this site to me. I started using the system about a month ago. My water looks fabulous but I can not keep my FC at the right level. I will shock up to 16, then by the next morning I am back to FC of 0.5. I read some other posts about this problem so today I bought an ammonia test, but that came back at 0. Do I just continue to shock every night until I can hold my FC or should I try something else. Any suggestions are appreciated.
My numbers right now are:
FC = 0.5
CC = 1.0
Alk = 120
PH = 7.2
CH = 250
CYA = 50
