I know Kush doesn't agree,

Correct.

but there's simply no need to have a UGF in a
planted tank... Why complicate your life that way?

Incorrect. It's not a complication, it's a different system. With a UGF it
is possible to keep your substrate really, really clean and extend the
viable lifespan of an aquarium system for years longer than is possible with
a static media bed where materials build up which eventually contribute to
the deterioration and ultimate demise of the system. THAT was a run-on
sentence.
