Would diluting the 50 ppm CYA reference solution 1 to 1 with tap or distilled water create a 25 ppm CYA reference solution?

CYA reference solution question

Maybe, but more importantly, the K-2006 and most CYA tests only read down to 3o. The TF-100 does go to 20 but I see little reason to test repeatedly that low.
In my case with an indoor pool I try to maintain a CYA level between 20 and 30, the addition of a 25 ppm reference would potentially make this an easier task as it removes or at least lowers one more variable.
Maybe a silly question, but you do not mix it with anything right. You just test directly and then in reality it is never consumed.
Seems like someone in Tucson should buy this

No, it gets mixed with the CYA test reagent exactly as if it was pool water. The mixture lasts 5 or 10 minutes and isn't useful after that.
OH ... got it.
Is the 5-10 minutes true for the regular CYA test? Not sure I have gone that long, but often it sits for at least 5 minutes before I get around to going outside to do the test.

Yep, 5 to 10 minutes from when you are done with the 30 seconds of mixing. The water sample from the pool can wait a long time before you add the CYA test reagent without problems.
The whole point, I thought, was to perfect your testing technique.
If you mix it up as directed and get something besides 50, you need to change the lighting or how far you hold it or decide just how invisible is invisible.
Once you get 50 consistently, if you repeat the test under the same conditions, your CYA reading should be accurate no matter what the CYA level is.
