Greeetings All,
I found this post by OTPirate going back to 2018. Is this still a valid procedure, particularly what a CYA of 50 should look like? Best, Lyman
"The CYA standard is so you can adjust yourself to the standard, not the other way around. I trust the chemists at Taylor Technologies whom manufacture the standard.
You do not use any pool water to use the standard-it is the pool water. Fill a mixing bottle half of standard, half of R-0013 and pour to 50 ppm in whatever testing vial (view tube, comparator) you are using. That is what a CYA of 50 looks like.".
