Thank you Watermom!!! I think the problem is: the new post section does not show up at this time ( although it did earlier today).
Anyway- I did find some OTO from a neighbor who had 2- and tested for chlorine and got zero again. Just to see that the OTO was indeed fresh and working I added a drop,of bleach to some water and tested it and it came out dark orange. So I think we an say that my pool has zero chlorine in it, however LOTS of CYA.
