Well, I fell like I've confirmed it with baking soda and a little neurotic experimentation (for alkalinity reagent anyway, while creating DC standard IIRC), but I guess I could be wrong. But I really don't feel like debating it, it's a negligible difference for what we're doing and the OP's water is considered soft either way they read their GH. All I can say is I've been able to change the degree of color change with a little added RO or bicarb. Try it, lemme know how it goes for you.
