The pool builder wouldn't let me add any chlorine until Sunday 8/20- so no I haven't. Of course the first couple of days the sun burned right through it - so it was zero in the evening - I'd add enough bleach to get to about 5ppm, but held through the night.

I have not added any CYA - except what is in the pucks. I added about 2 1/2 gallons of bleach between Sunday and Monday, but haven't had to add any since then - on Monday evening (between the bleach and the pucks) I had .5ppm-1ppm at sunset. Tuesday evening - I had 1ppm without any additional bleach. I didn't test last night (had class)

Also - I expect that there are "some" organics in the water - we've had the dog in and the kids every evening. Plus there is some dirt/sand in the bottom of the pool, PB says the finish manufacturer won't warranty damage from the little robot vacuums if you use one in the first 28 days - so that could cause some depletion.

I hear that it takes a lot of reagent to complete this test and I don't want to test unnecessarily.
