Received my test kit and I'm not sure what is going on. I have the Taylor K-2006 kit with FAS-DPD. I used the 10ml water sample in the large tube, 2 scoops of powder (which turned pink as it should) and so far 75 drops of R-0871 but water is still very pink. I hate to waste the whole bottle of reagent. At this point I am at 75 X .5 = 37.5 ppm free chlorine. Any ideas?
