is coconut coir good for planting succulents by itself and is aggregate diatomaceous earth the same as Food Grade?

I use Coconut Coir, Pumice and mushroom compost for planting my succulent containers, but someone told me I should be adding aggregate Diatomaceous Earth 1/4 in the mix and I can’t seem to find anything on that, only the powder and food grade.

Here is a recipe for succulent potting media. Food grade is the only type of diatomaceous earth to use around home or garden and I don’t really see any need to add it to succulent mix.
