Hi again avons82, I was just curious about the gravel.
If you want to, you can put gravel in a pond, There is available a "spider filter" that relies on the pond floor being covered in gravel.

However. They don't make it clear that you need at least 4 inches depth of gravel covering the filter, now imagine a big pond with 4 inches of gravel on its base, that?s a lot of gravel that will at some stage need cleaning.

I would also point out that a conventional biological filter and UV is much easier to maintain.
