TF-100 Test kit came today. Only real question is reading the TA. Is it considered red when the water turns pink/deep pink? numbers:
12:30pm . . . .7:45pm
FC=18.5 . . . . FC=13
CC=3.5 . . . . .CC= XX
TC=22.0 . . . .TC= XX
pH=7.5 . . . . .pH=7.2
TA=130 . . . . TA=140
CYA=25 . . . . CYA=30
Stabilizer dissolving in sock put in 7/24 when CYA was 0 according to pool store guy. I'm afraid I'm being too exact as to what is "red", in which case my TAs are actually lower. Thanks
