Pamsel,
It would keep things a lot less confusing for the responders if you would start your own thread instead of adding a question to an existing thread....you're way more likely to get good answers, and the responders are less likely to get your situation confused with the original poster's problems..
To answer your question, you need to keep adding the acid until your pH starts to move, because it has to come down for your alk to be lowered.
And to measure Cl higher than 5, you can use CarlD's dilution method for a ballpark Cl reading with the test kit you have, or you can get exact measurements up to 50 ppm from the dpd/fas chlorine testing in the PS 234.
Thanks
Janet
