If calcium is the only reason to use one over the other, you can always use
limestone in your waterworks (like waterfalls and such), and still use the
sodium bentonite, if it is more readily available, which I believe is the
case.


I don't think limestone would work in my water, it would probably
grow. Our city water is hard, it runs from 600 to over 1000 ppm tds.

I'm not promoting the koi clay, I just read a couple articles in
magazines and thought I'd give it a try. An uncontrolled experiment,
any results are meaningless, but it was something to do.

Snake oil maybe, but if your snake squeaks...
