Why is it when I check my FC with the K-1000 kit it will give me a reading on the first drop and by the 5th I’m at 10ppm but when I check with the TF-100 kit witch it tells me I’m at only 2.5 my goal here is to be 5ppm. Just Wondering why the K1000 shows are reading on the first drop.
K 1000 versus TF 100

OTO isn't especially reliable.
That said, the OTO tests total chlorine. Are you testing FC and CC with the FAS-DPD?
