For Scottturner: You do lose the DE after backwashing. If you add DE to a sand filter, only add enough (start with a small handful) of DE to make your pressure rise by 1 psi. NOte that it takes a few minutes for this rise to happen, so give it a few minutes before you add more if you don't see it rise immediately. If you overshoot it, just backwash it out and start over.
