Just a quick question. Is the R-0013 CYA refill pretty universal? Meaning, it isn't different from Kit to Kit? I am asking because I've noticed specific variants on what kits it's for and what type it is. I initially bought the K-2005 and bought the FAS-DPD add on from TFTestkit.
Here's the different CYA reagents from Amazon:
TFTestkit has CYA reagent but the description says the following:
A direct replacement refill for the TF-100It can also be used as a refill bottle for the smaller bottles found in the K-2006 and the TF-50
