For those of you who have a Taylor test kit...When you test for chlorine (not when Slaming) do you normally use a 25 ml sample or a 10 ml sample?

10 ml sample gets the job done for me. Resolution of 0.5 ppm is close enough for TFPC.

Use a 10ml sample for daily use.
A 25 ml sample possibly when doing an Overnight Chlorine Loss Test.
Take care.

Mostly using 10ml, but when you do your CC test, it is only accurate to 0.5ppm. The 25ml test is accurate to 0.2ppm. Not sure if this is an issue, since I believe CC isn't a problem until over 0.5ppm? (pool store says anything over 0.2ppm a problem)
The test was designed for 10 ml sample.....both FC and CC. Anything else is overkill but some like the precision of .2 ppm.
I don't know if this is "wrong" per se, but when I use 10 mL and the solution is darn near clear but just a tinge of the slightest bit of pink, to me that's "+" and not quite enough to call it "+ 0.5"
Edit: I still put the last drop in to turn it completely clear and make sure my eyes aren't fooling me.

Then, that's the end of the test. The test is not finished when you see a slight tinge.....the test (and all drops based tests that we use at TFP) is ended when the last drop you add makes NO further color change.
I see, and I apologize, I don't want to propagate poor practices. So does that mean the last drop counts when you're calculating the concentration? I believe the answer is no on that one, but I want to be sure.
Thanks!
If you see that tinge of pink you're not done yet. One more drop makes it clear...then add *another* drop and if that doesn't make it any *clearer* you're done and you do not count that very last drop.
