Calcium bentonite is similar to the ingredenients of kitty litter.
It's both absorbant and charged. Suck. Zap. Everything dissolved in
the water, now in the bentonite. As a bonus, it also releases trace
minerals into the water, that the koi like. Google for it.

I used regular plan old kitty litter from Wally World and it worked. Now
this may be a coincidence, but everything cleared up but one pool of fry
that was greener than green. :-) I guess I'll just toss some more in that
one and see what happens.
