I have a pond of 1mx2mx.75m and need a filter system

There are a number of fake flower pot filters pictured on my website. Click
on *My Filter* (website below) and scroll to the bottom to see them. This
gets the filter out of the pond, thus easier maintenance. One puts the pump
in the pond in 2 mesh boxes like this:

maintenance free (no filter material in the baskets, just the pump). ~ jan
