I have a question regarding replacement for my Cyanuric Acid Reagent.

I am currently using a HTH 6way tester and I quickly ran out of the Cyanuric acid Reagent. I cannot find a HTH replacement.
This is my HTH 6way tester from Walmart.


This is the Cyanuric Acid Reagent tester.


I then found this Taylor Cyanuric Reagent replacement on Amazon.com.


Question is can I buy the Taylor Cyanuric Reagent and still use my HTH tester tube and the #9191 bottle?
