Can I add DE to a sand filter that is used with an SWG? I read the article on adding DE to a sand filter and thought it sounded helpful. I went online to order DE but the specs page said it was not compatible with SWGs. I don't recall reading that in pool school so I wondered if it meant that a DE filter is not compatible w/ an SWG or if adding some DE to a sand filter shouldn't be done with an SWG at all?
If adding DE to a sand filter with an SWG should never be done, please be sure to mention that in the pool school article.
