The heart of the system is the skimmer and bio-falls. These units remove dead leaves and other things that may fall into the pond and provide a home for healthy bacteria that maintain the ponds natural balance of nutrients and acidity.

Plants and fish provide the other parts of the natural ecosystem. If the pond is properly deigned the fish and most of the plants will over-winter without problems, even at 40 below! The added advantage of a year-round pond is the amazing ice sculptures that decorate the stream and pond during the winter season..
