There are three brands that I know of that are marketed for koi. Koi Klay,
TerraPond, and Refine. All are calcium bentonites/montmorillonites. The
people that market TerraPond also have a clay capsule that they market in
the health food stores. Supposedly helps with your digestion, supplies
minerals, etc. etc. The manufacturer stated that a lot of third world
country women, particularly during pregnancy eat clay soils to get the
needed minerals.

Nedra, where did you find calcium bentonite? Most bentonite I've seen
here has been sodium bentonite, and when I ask about calcium bentonite
am told there is no difference between the two.

Hey Lee ... Is the calcium bentonite clay the same thing as
Koi Clay? I do hope so ... I just bought a bunch! ...
