Diatomaceous Earth is a natural occurring siliceous sedimentary mineral compound from microscopic skeletal remains of unicellular algae-like plants called diatoms. These plants have been part of the earth's ecology since prehistoric times. Diatoms are basic to the oceanic cycle, and the food for minute animal life which in turn becomes the food for higher forms of marine life. As living plants, diatoms weave microscopic shells from the silica they extract from the water, then as they die, deposits are formed and then fossilized in what are now dried lake and ocean beds. The material is then mined, ground and screened to various grades, for the countless uses in today's products and processes, from toothpaste to cigars, plastics to paprika, filter media in swimming pools to home fish tanks, as well as insect and parasite control in animals and grains.

Diatomaceous Earth is a natural (not calcined or flux calcined) compound with many elements which include:

Silicon Dioxide         SiO2         83.7%
Aluminum Oxide         A1203         5.6%
Iron Oxide         Fe203         2.3%
Calcium Oxide         CaO         0.4%
Magnesium Oxide         MgO         0.3%
Other Oxides                 1.9%
Ignition Loss at 1000                 5.3%
