Combined Chlorine Test


May 4, 2022

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.

Be careful not to let it sit or the pink will return.
Do the drops (1 drop per second) & call it.
Also clean the beaker with alcohol.
They can get dirty & give false positive cc results.
A cc of 0.5 is not a problem in an outdoor pool with adequate fc levels. FC/CYA LevelsThe sun will take care of it.
