40% Improvement form yesterday, the water is blue and clear in the shallow end (4ft deep).
with water chemistry as follow:
FAC-3
PH- 7.2
TA- 110

The problem now is, can not hold chlorine every day I pour 24 Qt of 6% Bleach at night time, 12 hours later FAC reading is .5, what can be done/ Should I raise CYA level?
