The only other thing I can think of is if your pH drops low, some rock and sand could dissolve. The pH would have to drop below 7.8 however and it's not likely with a dKh of 11.8, but possible if your home has very high CO2.

Of course, if the LFS tested for you, they could have the same “bad” test kit as you
