Freshwater Organics has been distributing the purest organic food-grade diatomaceous earth available for over 5 years online and we take great pride in the fact that we sell the highest quality DE available. When we started, there were only 3 or 4 pages that would come up in an Internet search engine. Today, there are 130,000. That means that the message about the benefits of diatomaceous earth is finally getting out. That is great news for all of us, and competition is a good thing. As an international distributor of Perma-Guard Diatomaceous Earth Products, we sell ONLY the highest quality DE availble - bar none. This is not a side business... this is my only business. I don't carry several "grades" of DE or shop for bargain bags of DE... I distribute Perma-Guard products because they are the best! From time to time, we poke, drop, or damage packages so that they can not be shipped. A few months ago, I damaged several 50# bags and rather than return them to the warehouse to repackage, I simply listed them as bulk DE. The response was fantastic. That tells me that some people want the lowest price that they can get on DE and don't care about fancy packaging. Now, I will caution you that there are some very unscrupulous people out there selling DE on Ebay and other sites that are offering DE in zip lock bags for sale. I do not advise buying from them at any price - unless you know the company and can verify that their product is pure, food grade DE from a freshwater source. There is no way of knowing what they are selling, what quality DE is being offerered, or even if it is food grade. I will tell you this; What I am selling as "bulk DE" is Perma-Guard Fossil Shell Flour. Due to government regulations and legal limitations, I can not "re-label" it without going to a great deal of expense and trouble. Therefore, if you would like to buy bulk DE from me, you have my assurance that it was scooped or poured from a Perma-guard bag, that came directly to me from the mine. It is organic, pure, food-grade, freshwater diatomaceous earth. Legally, I can not put a label on the bag saying so - but when you receive it, mark it as food-grade, so that you don't mix it up with any other white powders that you may have laying around. I have always taken pride in the fact that everything on my site has a satisfaction guarantee. Naturally, because there is no way I can prove that white powder in a box is my product, I will not be able to extend that guarantee on the bulk orders. If these conditions suit you, then you may order bulk DE at some very nice discounts. This will come in a plastic garbage bags, shipped in a box. This is ideal for pets, horses, chickens, goats, pigs, slugs, grain storage, to absorb odors or oil spills, or any other use you would have for food-grade DE.
