Taylor CYA test

[cj133]

Hi all,
Every time I try to test my CYA using my K-2006C kit I'm always left with the same unsure feeling.
Am I making this test more difficult than necessary or is there a better way to test CYA?

The Taylor test is about as good as it gets for a residential pool test. There are some very expensive photometric measuring devices (turbidity meters) that use blanks and NIST standards and can get you accuracy down to 0.1ppm or lower....but they run north of $500. So not really something your average-joe pool owner can afford.

Simply following the testing guidelines here on TFP and the Taylor website and you'll be fine. It takes some getting used to but once you master it, it's an easy test. The test itself really is only good to +/-15ppm, so don';t sweat trying to make an exact value. Just do the test a couple of times by reusing the same solution by pouring it back and forth between the mixing bottle and tester and then average the results. Round up to the nearest 10ppm and call it a day. Bright sunlit days (high noon) is the best time to make the measurement. Indoor lighting will skew the test and give false results

you are not alone.
i feel much better using the blue devil cya tester than the one supplied with the k2006c

I also find it difficult to do this test and to have confident results. I am always unsure if I see the dot or not.
I tried indoor. I also tried outdoor with the technic mentioned frequently here but I see no difference between the two.

You can always try the view tube with the moving dot on the arm (#4088). Some people find it easier to use.

Uses the same reagents for testing.

This.

I'm a chemist for a large petroleum services company and have full access to millions of dollars worth of analytical equipment. I used to bring my water in to work to run tests on it using high-accuracy instrumentation (used an LC-Mass Spec for Cyanuric Acid, for the record). While it very much appealed to my geeky nature to go this route, the realized advantage it gave me over using a home test kit was exactly nothing. With all of the variables involved (rain, evaporation, age/quality of chemicals, kids, pets, etc...), you're never going to be able to control your pool chemistry within a bracket so small that it requires this kind of accuracy.

Trust the force. Trust your gut. Don't overthink it...

Does anyone make that with increments that don't jump from 60-100? I do like that one, but with a SWCG calling for a little higher CYA it would be nice to have something that shows 70, 80, etc.

Standard Taylor one does.

I meant one that has the dot on a sliding thingy...whatever you call that!!
