I have not checked my CYA for a couple of months, last time it was 40. I just checked it using a new 8 oz bottle of Taylor R-0013 and it isn't cloudy at all.
I did the test twice, carefully measuring the pool water to the bottom of the label and then filling to the top with R-0013 and shaking, then letting it sit for 30-45 seconds and shaking once again and pouring into the black dot tube.
My other test results are:
Cl =3.0 and I know I need to add some, it's the end of the day
Is this normal for it to go to 0? Looks like I need to read about adding CYA.
