Pool has been clear for7-8 months. Now I get yellow brown dirt like forming on surfaces. Brushed a few months ago and now it is back (also added quat algaecide) I understand that high levels of CYA and CH will prohibit chlorine form sanitizing. My numbers don't seem to be too high:
FC - 6.8
CC - 0.4
SALT (ON DISPLAY) - 3200
CH - 190
PH - 7.8
CYA - 60
TA - 100
Looking for some input. If I am to stay out of the pool store i need to know what to do from here.
Thanks,
