Is there a test out there that ONLY measures Combined Chlorine? I am currently using the Taylor K-2006C test kit and am having trouble pinning down an exact combined chlorine number. When I test using 10mls in which 1 drop = 0.5ppm, the combined chlorine reagent does turn sample to a slight pink and goes clear after adding 1 drop which would indicate a combined chlorine of 0.5ppm or less. When I tested using 25mls in which 1 drop = 0.2ppm, the combined chlorine reagent does turn sample slight pink, but never really seems to go completely clear after multiple drops.
