I'm sure that someone here will know. Next time I'm there, I'll look.

What does it say it tests? For CYA, it should come with a separate tube with a black dot on the bottom, with a graduated scale on the side for ppm.

I have the five way kit from walmart and it does the CYA test, it is the larger kit, and I doubt that you have it if it is only the four way one.
