How much DE do you add to the skimmer? I take it in a regular sand filter that you lose the DE after a backwash? Thanks.

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.

Scott --- you don't say how big your pool is so it is hard to suggest an amount. But to give you some idea --- I have a 24ft AG, a 1/2 hp fullrated inground pump and a 200 lb. sand filter. I usually start out with adding about 1/4 of a cup of DE and then go from there. The first time I did it, I didn't see a 1 psi rise, so I added more and then it was too much. After that, I learned that you have to wait a bit --- maybe even 1/2 hour to see the increase in pressure, so be patient and don't add any more until you give it a little time. If after 1/2 hour, no psi increase, add just a little more. You'll soon learn how much you need after a couple of tries.
