Product Spotlight

Celite Diatomite

Celite diatomaceous earth grades are made from the fossilised remains of single-celled plants called diatoms. These microscopic algae have the unique capability of extracting silica from water to produce their skeletal structure. When diatoms die, their skeletons settle to form a diatomite deposit.
