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...

If your city drinking water has TDS of 600-1,000 ppm, it outside of EPA's
National Secondary Drinking Water Regulations, which set the recommended
maximum contaminant levels (mcl)for TDS in drinking water at 500 ppm.
These are non-enforceable guidelines at the Federal level. However, many
states have adopted them as part of their own drinking water standards.
You should check with your state to see what the allowable mcl for TDS is:

http://www.epa.gov/safewater/mcl.html#mcls

See the chart at the bottom of the page.



The statement that the city sends out each year says they can go to
1000. They got their wrist slapped a couple years ago for not
reporting the 1040ppm that they sent out, got fined or something.

It's a good thing it's not enforceable, they'd have to turn off our
water.
