The instructions (Taylor) say for the 1st test "record as ppm FC." The next step, after 5 drops of R-0003 says record as TC. Last part says "subtract FC from TC. Record as ppm CC. Formula: TC-FC=CC. After step 1 it shows 2. After step 2 it shows 1.

So, I am confused, do I have 2 ppm FC, 1ppm TC and 1ppm CC? That's not posible right?

Thanks again and again!!
Are you employing R-0001 and R-0002 reagents? If so, that's the DPD chlorine test. You have the Taylor K-2005 (or equivalent). See http://www.taylortechnologies.com/pr...er&Number=5136

Carl is likely referencing the FAS/DPD chlorine test found in Taylor K-2006, which uses R-0870 powder and R-0871 reagent to affect a pink color that disappears when the right amount of R-0871 is added to the sample.

If you're using the DPD chlorine test (R0001, R0002, R0003) the correct amounts are:

TC = 2 PPM
FC = 1 PPM
CC = 1 PPM
