DE helps the sand filter out finer particles. You have to be careful that you don't add too much and clog the filter. I believe you add a little at a time until filter pressure goes up 1lb. Btw, I have no experience with sand filters. I've only ever had a DE filter.

Does someone else here have the link to the DE procedure for sand filters?
