Swim ponds are unique works of art. A natural swim pond does not contain the harsh chemicals that a traditional swimming pool does. It is safe for fish, plants, and children. It differs from a typical koi pond in that the filtration is kept separate from the swimming area to ensure safe and clean water. Plants, grass, and flowers can actually grow around your swimming area, unlike a concrete swimming pool. They are fun, beautiful, and a perfect fit for your backyard.
