When
you try to backwash a bead filter the biggest problem is large masses
of beads stuck together by the waste material. Specialized blowers are
often not enough to break them apart and remove the debris. It isn't
unusual to see the pond owner with the filter apart breaking up the
clump with a stick. Bead filter manufacturers list ease of accessibility
to the beads as a selling feature because this is often necessary.
