I've got the K-2006 test kit and have been testing the chlorine levels in my newly opened pool...needless to say I'm trying to keep it at shock level but what I've noticed is that once I put the drops in to make my sample go from pink to clear if I wait awhile it goes back to pink. Am I waiting to long for no reason or should I go with the first reading that I get?
Thanks
