Our pond is located in our tropical area, surrounded by bamboo and lovely tropical plants.  We have a small deck nearby with a patio table where we can sit and enjoy the beauty.  The pond starts with a waterfall.  The upper pond is about 1000 gallons and about 2' deep has water plants and about 8 goldfish.  The lower pond is about 2000 gallons and slopes from about 18" to 3' in the main area.  We have about 10 koi (about 6-8" in length).  We use a bubble filter to help keep the ponds clean.
