What is diatomaceous earth?

Diatomaceous Earth (DE) is an extremely versatile natural product that is derived from pure fresh water sources. It is a sedimentary rock that is made up of underwater single cell animal remains known as diatoms. DE powder is in turn produced by processing these rocks. Enriched with minerals, Diatomaceous Earth offers numerous benefits and has many uses which can be found here.

Our freshwater DE is taken from the ancient freshwater lakes of Mount Garnet, Far North Queensland. We process the Diatomaceous Earth directly from the mine, enabling us to ship diatomaceous earth in Australia and internationally.

Diatomaceous earth-where to buy:

As a leading diatomaceous earth supplier, we pride ourselves on the quality and range of products and welcome enquiries or browse through our collection of DE grades and buy diatomaceous earth here online today or visit one of our dealers to experience its numerous benefits.

A word of CAUTION: Do not confuse natural silica or food-grade Diatomaceous Earth with industrial grade DE which may contain crystalline silica. Crystalline silica is dangerous to inhale and must not be consumed by humans, animals, or used on gardens and agricultural crops. Recent news reports have highlighted the dangers of "silica" - this is referring to crystalline silica which comes from building products when cut or abraded and NOT natural amorphus silica. 

Our food grade Diatomaceous Earth is regularly tested by registered labs which confirm it contains an undetectable amount (less than 1%) of crystalline silica. This product is regarded as safe by the USFDA.
