Coral snow alternative

[Icefire]

I thought Coral Snow was Calcite Chalk? (CaCO3)

[Proteus]

From what I read a little says yes along with Magnisium

Where can you buy the stuff? At a winemaking kind of place, maybe?

I checked wine stores and the product is expensive and granular.
I bought off of Amazon and health food stores.
I just checked Amazon and of coarse with the falling dollar it's $35 a pound.
Make sure it's food grade

Something like this? But seems way cheaper than #35/lb so maybe it's the wrong stuff? http://www.amazon.com/Grade-Pound-Wy...rade+bentonite

Yep good deal. Same stuff

So I did a bunch of hunting around. A biologist that I'm familiar with says that bentonite has enough copper in it to be detrimental to a reef tank. He also said he's analyzed Coral Snow and it is a type of clay, but he can't divulge any more information than that. It is not chalk and it is not bentonite.
