    Vacuum and wash filters again. I can't think of another answer but that maybe would work. Keep an eye on pressure. You may have go to clean 2x Although no one would knows how much you put in ?

    I put about 4 pounds into the skimmer.
    I completely cleaned the filter, but I'm still seeing a little DE powder stuck to the cartlidges.

    That isn't surprising, and you may find reduced performance from your carts after you can't find any more at all. Some may embed itself into the fibers enough to create a need for replacing the filters, but I wouldn't do that until I was sure I got all the DE out of the pool.

    No worries, clean and utilize till they don't perform.

    Maybe a little backwashing will go a long way.

    Cartridge filters get washed/rinsed with a hose, no backwash option.
