I missed it somewhere…how do you know you’re losing Ca?
Water test kit for calcium. Beerery suggested (reply #64) sending samples with and without BTB to Ward Labs and I took the DIY approach.

To follow up: After a busy week, I had the chance to repeat the above-mentioned water test a few times. Joe F says gallotannin does not chelate Ca. Now, I hate to question authority (riiight… ::)) but calcium keeps disappearing, and the higher the dose of BTB, the more calcium goes away. Somehow BTB is removing calcium. That’s all I know.

Cool…thanks. I think I’d want to have the result verified by a lab, though.

Yeah, it has occurred to me that it’s possible BTB is somehow interfering with the indicator or reagent in my test kit. But in practice, I just won’t go with such minimally mineralized water as when I started this, just in case the effect is real. Outside of Pilsners, it would probably never be an issue.
