who use bog
filters have chosen a natural form of filtration for
their ponds. Bog filters, also known to some as veggie filters, are
used as part of a natural biological filtration system. One of the
main purposes of this system it to control algae bloom.
So, what is a bog filter? It is a wide and shallow pool that is filled
with small gravel where the water flows from end to end. It is generally
about one to on and a half feet deep.
It is filled with many pond plants that have been deliberately starved
of nutrients. Why? Because then, in order to survive, they must absorb
all of their nutrients directly from the pond water. This increases
the health of the water (no excess nutrients for pond algae to feed
on). And, of course, the addition of so many pond plants can also
increase the beauty of the pond.
Why not have a such an environmentally friendly filter for your pond?
Depending on where you want your pond and what sort of landscaping
you are doing, you may find that a bog filter is the perfect solution.
