Well, this morning brings zip zero chlorine. I want to say that I could see a tinge of yellow in the test bottle, but not enough to register on the lowest level of the vial. Since I don't have the fancy test kit, I used the test strip to check stabilizer and it indicated it was in the "ok" range. My stockpile of bleach is now gone so off to the store again. The water is clear, thank goodness. Nothing worse than looking out your windows and seeing a cloudy pool or green pool for that matter. Now I do realize that I need a better kit, but will not have that for a while. What will actually resolve this chlorine lock and what kind of time frames am I looking at? Thanks everyone.
