What is Diatomaceous Earth?
Diatomaceous Earth is a fossilized deposit of microscopic shells created by one celled plants called Diatoms. These plants inhabit all the waters of the earth, and serve as the basic food for aquatic life, just as grass is the basic food for land animals.
Perma-Guard products use Diatomaceous Earth, mother natures eco-friendly naturally organic material.
Our products fit into the "Living Green" lifestyle. Actually, Diatomaceous Earth is not an earth. It is the fossilized remains of microscopic shells created by one celled plants called Diatoms. Not all deposits of Diatomaceous Earth diatoms present in those deposits are the same. Perma-Guard's FOSSIL SHELL FLOUR® is a very pure form of Diatomaceous Earth used as an anti-caking feed additive.
What is Diatomaceous Earth
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 food grade products.
