Red Lake Diatomaceous Earth is completely safe to be used with all types of animals. Please note, this does not include reptiles or amphibians.

The difference between pool grade and food grade diatomaceous earth is a result of the way in which the natural diatomaceous earth has been treated.

Pool grade diatomaceous earth is only meant for use as a filtration aid. It has been treated at a very high temperature (this is referred to as calcined) and contains a very high percentage of crystalline silica.

Food Chemical Codex Grade diatomaceous earth, on the other hand, is treated at a much lower temperature (non-calcined) and contains a very low percentage of crystalline silica (Red Lake Diatomaceous Earth contains less than 1% crystalline silica). Food Grade Diatomaceous Earth must also meet strict specifications in regards to heavy metal content.
