A veggie filter is a setup where you run your pond water through a
plethora of plants. In our setup we run the water through a tank filled
with water hyacinth (which I don't think are available in your area)
and then into a waterfall filled with watercress. The plants filter the
fishy waste and use up a lot of the nutrients that single cell algae
thrives on and keep the pond clear. The roots of the plants catch a lot
of the mulm and dirt.

We can get water hyacinth but tend to use them as annuals as I have
never managed to find a solution to keeping them over winter. They have
been spread in various directions from my indoor tanks to buckets in the
green house but all usually die. If anyone know how to overwinter
successfull it would be a great help. If not I tend to by some more of
ebay each year.
