CYA is sold both as powder and large granules. I think the powder is about 2 oz wt to 1 fluid oz. The granules would be less, but I'm not sure how much less.
Probably, you should add 1/4 cup of powder or 1/3 cup of granules . . . and then retest.
Finally got the test kit last Thursday. I was indisposed until today.

Looks like I need to add 5oz ,by weight, of CYA. What volume is approximate, assuming 99.9% Cyanuric Acid?
