18-20k gallon gunite pool with fiberglass walls.
Brand new k2006 test kit numbers -
FC - 1.6
CC - .2
pH - 7.6
Alk - 80
CH - 60
CYA - 0
The water is clear but is slight yellow-brownish (see pics). I know I have to raise my CH to between 250-300 and I'd like my CYA in the 40-50 range.
I did scrub and vacuum the pool.
What should my next step be? Any/all help is appreciated. Thanks!
