How did I not know about this before? It is so much more simple and repeatable than the Taylor kit that I’ve been using for years. Any drawbacks?

The Pentair product is a relabled Blue Devil CYA test kit. The only drawback is since the measuring vessel is larger, you use more reagent than with the Taylor test. The Blue Devil test uses about 18ml verses 14ml for the Taylor.
Awesome, I had no idea... It looks like the Pentair kit has enough reagent for twice the amount of tests than my Taylor 2006
You can easily pick up a big bottle of regent for the Taylor kit. 16oz
Or...

Taylor sells a very similar “pull stick” style tester. It’s the same exact chemistry as the regular CYA test and so the same limitations/tolerances apply. One problem you can run into is if you raise the stick too quickly, the particles in suspension in the test solution can get perturbed and that will change how easy it is to see the black dot. So lighting and technique is key.
Unless one is using an inline chlorinator with trichlor pucks and powdered shock, CYA testing shouldn’t be more frequent than once or twice per month. So buying large bottles of reagent may result in waste. It is possible, although somewhat unusual, for the CYA reagent to go bad.

When reading using the Pentair kit, do you read in bright sunlight, or shade? (This makes a big difference on the final reading)
The directions on my blue devil that arrived today did not say to test with back to sun.

Regardless what they say, your back to the sun will provide the most consistent, repeatable, and accurate results.

The only trouble with the Pentair CYA test is, if your hands shake, it can be hard to get a reliable reading. My hands shake something awful due to medication, and I couldn't get a reading to save my life -- I had to get my husband to read it for me!
That and the amt of reagent you have to use made me switch to the TFTestKits CYA test kit. Looking down the little tube is SO much easier for me!

At their core, they are all the same test with the same level of error. There’s just no easy way to measure CYA that gives highly precise results. Whether you’re moving the dot up and down or the liquid level up and down is simply a matter of which you find easier to read. I have no problem with the Taylor version of the fixed dot CYA test. Others find it impossible.
