While we didn't build this pond, we have retro-fitted it with a new external filter that does a great job of keeping the water clean.  Meanwhile, The landscaping in the backyard needed to be updated.  We took up the entire flagstone patio, leveled it and re-laid it with a new sub base.  then We added a new arbor and patio area to give the owner a quiet place to sit and meditate.  Low voltage lighting was added and now the yard takes on a whole new look.
