About 3 to 5 months ago I saw an article about ponds either in FAMA
(Freshwater and Marine Aquarium) or AFM (Aquarium Fish Magazine) that
advocated building a 'mini-marsh' with lots of emergent aquatics next to a
pond and circulating the pond water through it.  The author claimed that
this system would clear the algae and give the pond very clear water.  It
sounds believable.
