DE, also called Diatomaceous Earth, are the bones of tiny anamils and algae that lived millions of year ago. It's used to coat the grids of DE filters.

The dirt is trapped in the DE on the grids and is back-washed out, similar to a sand filter. Then fresh DE is put in the skimmer and re-coats the grids. About once per month you should take your DE filter apart and clean the grids, then re-coat them with fresh DE.

DE filters are a bit more expensive but if you have to have the best water, DE is the way to go.
