So, we attempted the CarlD Shotglass method of testing our water, but it didn't seem to work. No matter how much we diluted (1 to 2, 1 to 3, 1 to 4, etc.) it always read at .2. Can't figure out why.

So now we have no idea if we have enough bleach in the pool to have reached shock level or not... and I'm not exactly sure what we'll do tomorrow when we need to test the water again and add more bleach. Yikes.
