Lesson: If you keep adding chemical, and your test continues to show no change, at some point you need to doubt your test.
New pool. New test kit.
Not using salt yet.
Add calculated volume of bleach. A little change, up to .5 ppm.
Continuing to add cya, meanwhile adding more bleach.
And more bleach.
And more bleach.
Still .5 ppm Cl.
Wife: I'm beginning to doubt our test kit. I'm going to WalMart and buy another kit or more reagent.
New kit: Well over 5 pmm Cl. (last night)
This morning: Report from her lab: Well over 5 ppm
Evidently Cl reagent can go bad (or if not bad, at least neutral... which is.... bad), and sometimes does. Know that.
