My water looks great but my latest test was:

PH 8.0
TA 110
FC 12??????
CC 0
CYA 80
CH 350

I let Leslie test it and they came back with

PH 7.8
TA 60?????
FC 4.0
CC 0
CYA 70
CH 210
Salt 3700 (odd bc this is the highest reading I have ever had and I haven't added salt all summer and just added a little water)

Could my FC reagents have gone bad?
