Hi, After reading a post on diatomaceous earth I decided to purchase some and try it for silica supplementation and parasite removal.
My question is, is food grade diatomaceous the same grade as is used for feeding animals and livestock? I read not to use the aquarium or pool filter grade but don't know if there is a differentiation between human food and livestock food grade and of course the local feed shops have told me they are not allowed to say it is food grade. Thanks for any help you can give. PT
