"Perma-Guard is the original and largest supplier of fresh water, food grade Diatomaceous Earth products for agricultural use in the world.
Perma-Guard, with more than 40 years of experience, is the company known world wide for using a grade and quality of Diatomaceous Earth that is extremely pure. It was important to have a consistent shape diatom and no unwanted sediment. The shape of the diatom must be tubular with holes on the walls. It must be fresh water because the diatoms form a harder shell and is less fragile that those in salt water. Salt water deposits contain a mix of diatom species. These deposits shapes and sediments are inconsistent making them unusable for our products.
