Food-Grade DE vs pool DE Filter aid

[not_for_sale]

I ordered Food Grade DE from amazon and get this box that says its to be used in a pool filter. Is there a difference between filteraid used in pools and filteraid used in food applications?

I do not believe that pool DE is food grade.

Absolutely, do not use one labeled for pools. In all likelyhood, they did not sell you food grade DE.
