I've been trying to perform a CYA test for my pool. I have added what I calculate to be a CYA=60 for my pool in stabilizer. My measurement reading at 30 CYA (minimum level) to not be quite there yet. (See attached image).

I also attached an image at 60 CYA mark, and the black dot is definitely visible.

Neither of the two images matches the the photos on the Taylor website. BTW, I took a sample to Leslie's and they measure 60.
What am I doing wrong? I followed all the instructions from my K2006 kit, to the Taylor website, and the couple posts here as well.
Shake wait 30 seconds. wait 30 seconds... wait 2 minutes. Hold at waste level under the patio and out in sunlight with back facing sun... Same result.
