I have a couple of questions about what everyone is using for their CYA testing tools.
I'm using the Taylor Mix Bottle #9191 :
Here's the TFT Mix Bottle :

What is the difference between the Taylor Mix Bottle and the TFT Mix Bottle? Does the TFT Bottle work the same way as the Taylor bottle? For example, does the TFT bottle have the 7 & 14 ml marks with the procedure the same, ie, fill with pool water to 7ml, then R-0013 solution to 14ml ?
I'm also using a CYA Vial that came with a kit purchased from Leslie's Pool Store. The kit is an approximate equivalent to the Taylor K-2006 but the CYA Vial that I have is only graduated to 30ppm CYA.
My vial diameter is about 9/16" .
I'm looking at maybe getting the TFT Vial since it has the 20ppm range included :

- I read at the TFT store site that this vial is easier to distinguish when the Back Dot disappears. What is the diameter of the TFT Vial?
The other part of my question about CYA Testing tools is regarding the 2 Taylor Comparator Blocks.
Does anyone use either of these 2 Taylor blocks for testing CYA?
Taylor 9056 :
Taylor 9058 :
- How are these 2 Comparator Blocks graduated for CYA testing? Are they graduated from 20-100ppm ?
- Are the Taylor Blocks easier to use with distinguishing when the Black Dot disappears vs the vials?
