Filter or no filter??

[Steve Shapson]

My new pond has been filled for about 2 years now and I finally put a pump
in.
I've been told that having a pond with lots of plants and water flowing down
a stream with many stones can do the same thing a pond filter does. What
is the reason for having a filter?

Mechanical filter filters out wind blown debris from the pond. Bio filter
stabilizes the water so that we could feed the fish a lot.
