Those readings were with an old test kit and then with some old "dip and stick" checks. Once I received my K 2006 kit, I tested it and it was a zero. This was late last week.
I have added another bag of shock and used a couple of trichloro pucks. I have not tested the CYA since late last week. It appears that I was 3 more CYA tests left in my kit.
