Is all DE the same???

I've read somewhere that for the DLM to work properly you need to add food grade Diatomaceous Earth. I called my local Southern States and they have DE but said it wasn't food grade. Can I use this or does it really need to be Food Grade.

GOTTA be food grade. Or nothing.

ETA: You can buy DE on internet at the poultry supply houses (in small bags- I get the 40lb bags at my feed store).

Needs to be a Food Grade DE, nothing else!
