When using diatomaceous earth in the garden, it is very important to buy only "food grade" diatomaceous earth instead of the diatomaceous earth commonly used in swimming pool filters. The diatomaceous earth used in swimming pool filters undergoes a process, which changes its composition to contain a higher content of free silica.
