I love my new TF-100 kit, but it's missing one thing that is useful for me -- the acid demand test. I continue to struggle to detect the ever-so-subtle differences in shades of purple in the 7.6-8.0 range (where my pH always stays), and the acid demand test is an extra tool that helps me to know where the pH is. My previous (inferior) Pentair kit had the acid demand test, and it was useful to help me feel more confident in my pH reading.
Is there an "add-on" for the TF-100 kit to perform the acid demand test?
Thanks,
Phillip
