Perma-Guard Diatomaceous Earth, 50 lb.
Diatomaceous earth packaged under our FOSSIL SHELL FLOUR® label comes from an extremely pure fresh water deposit of the diatom Melosira Preicelanica. Why is this diatom so special? Its shell is made of amorphous silica. Its shape and hardness are important to how it works. Its hardness keeps it from dissolving in liquid. The holes along the diatom’s wall allow it to absorb moisture, hence its use as an anti-caking agent. Darker colored diatomaceous earth often contains an excess of a particular mineral such as iron or a high percentage of clay.
FOSSIL SHELL FLOUR® is almost pure white and consists of 89-94% Silicon Dioxide plus 28 trace minerals which means more diatom surface area is available. More diatom area means greater absorptive capacity and more improvement in the mixability and flowability of animal feed. FOSSIL SHELL FLOUR® does not swell, does not absorb nutrients and poses no long term hazard when used as an anti-caking agent in your animal’s feed.
