Delayed reaction with chlorine tests

[papa6]

Richard,
Yes, the water temperature is cold, 70 degrees or so......I just opened last weekend and have not fired up the heater yet. I will cap a sample tomorrow and let it warm up before testing. THANKS A BUNCH for the tip!!!!!! I will let you know how it comes out. Thanks again!!!

Also, the OTO test for total chlorine (turns yellow) can take up to a minute or two to fully develop

Chem geek and waterbear, I would like to thank you sooooo much for the insight you gave me on testing my water. I would never have thought that my water being cold could have an effect on the testing. The water is now warm and everything is working great! This was a simple answer for you, but a frustration for me, thanks again for taking the time to help me. This is why this forum is GREAT!!!!
