...An ordinary Hardness test kit measures both Ca2+, Mg2+, plus a range of other ions depneding on their concentration and how tightly they bind to EDTA...
I think that any sciewntist that tried to test this theory about Calcium
levels would rapidly find themselves in difficult experimental water with
a single rather shaky leg to stand on.
Sorry for this rather long post, I just thought that I should add a bit
in from a scientists perspective, even if I am running on the smell of
vegemite to gain a little "truth".
I found your posting interesting and didn't think it was too long. Being non technical can I ask you to fill me in on the meaning of EDTA please.
Bruce, I think that Peter has won another vegemite award! <G>
