does anyone know of a link to a list for all the uses of DE. i know the basics i think, but wanted to find as much info as possible. i just found a local supplier. yeah!! updated question: ok i picked it up today at a feed store. it does not say food quality. the brand: red lake earth. diatomaceous earth with calcium bentonite (not sure about this part) OMRI listed (organic materials review inst.) for: dogs cats cows chickens horses goats etc i think it said use less than 2% in diet. so do you think this kind will be ok? i am not to familiar with calcium bentonite. anybody else using this kind.
