new test kit - checking combined chlorine?

[waterbear]

stop when it turns colorless, add the R-0003 reagent, and if it turns pink again retitrate to get your combined chlorine. If you let it sit you will have inaccurate results.

THANK YOU Waterbear and Anna! It was driving me crazy that the water sample would turn clear and then after a minute turn pink again. I didn't know what to count! Again, thank you, thank you, thank you.
