I have the K-2006 and it requires a 7ml sample of 1:1 dilution with r-0013 for testing.
I bought a separate tube for CYA testing from TF-Kits and when I use the sample I made, it doesn't work well with this tube as I don't have enough liquid? Does this tube use a larger sample size? If so, which measurements do I use? And can I use a graduated cylinder to measure it out with the speedster?
