Is calcium bentonite clay finely ground and sold at excessively high
prices...........to ponders as a miricle cure all for ponds and fish.
I am not argueing it may have benefits, but the price certainly is not
even close in line with what you can buy a 50 or 100 pound bag of
calcium bentonite clay for, from a foundry supply, or feed mill
for......The jopker on Ebay is probably doing just that, and only
needs to sell one bag of the stuff and his 100 pound sack is paid for
in full.....Even with shipping, the cost of a 50# bag is still cheaper
10 times over than buying packaged koi clay and paying the price
gouging prices.

You can get a 100lbs bag of bentonite at an industrial pump or drilling
supply company for about $6-10/bag. Do a search on whitepages.com for one
or both of these businesses in your area, then call them and check on
availability. They also make it in pellets, which is much easier to use,
but a bit more expensive. The other advantage of pellets is that they come
in 5-gallon buckets that are resealable.
