Just received and used my TF-100 test kit last night. CYA was low at 30 and cholorine was low at 1-2. I'm a little confused about free chlorine though. How to I figure out what that is again?

Your initial test with the DPD powder (R-0870) and titrating agent (R-0871) five you your FC. You then add the R-0003 and if the color of the sample changes back to even the slightest pink, you count drops of R-0871 to turn it clear again. This gives you your CC.
