DE = Diatomaceous Earth

Here is link which describes what it is:

http://en.wikipedia.org/wiki/Diatomaceous_earth

From the link:
"The most common use (68%) of diatomaceous earth is a filter medium, especially for swimming pools. Diatomaceous earth has a high porosity because it is made of microscopically small coffin-like hollow particles. It is used in chemistry as a filtration aid to filter very fine particles that would otherwise pass or clog the filter paper. It is also used to filter water and other liquids such as beer. It can also filter syrups and sugar. Other industries such as paper, paints, ceramics, soap, and detergents use it as a filling material."


So for pools we use as a filter medium. For sand filters you can add a small amount which increases it's ability to filter smaller partcles. Here is a post describing how to do it:

You can purchase DE at most stores that carry pool supplies or online.
