WHERE DIATOMACEOUS EARTH FORMS
Food Grade Diatomaceous Earth forms by diatoms absorbing the mineral content within a water body to form a shell around their cell membrane. These diatoms, in this particular case, absorbed a high amount of silica and low amount of metals within this particular body of water in the Reno, NV region of the United States. Over thousands of years, these diatoms build up on top of each other forming a huge fossilized deposit. As a result, these diatoms formed when dinosaurs roamed the earth! Now, the diatom itself is a particular one called the Aulacoseira diatoms.
Food Grade Diatomaceous Earth is OMRI organic.
