I don't believe I've seen it mentioned here, but in the past it was discussed that one could add enough DE to a sand filter to raise the pressure by 1 psi to match the filtering capability of a dedicated DE filter but with the convenience of being able to backwash the sand (then add more DE of course).
Many that did this reported it worked really well.
Just curious if it's still working, and wanting to make others aware of the option in case it is
