Before ever buying Koi, you must create a proper environment or habitat for them. However, you should not rely on the opinions of just one person. It may be a good idea to do your own personal research on your own, before you go to purchase the materials needed for you pond. Because of its popularity, an unlimited supply of resources can be found on the topic of Koi keeping these days.  Visit your local library, or research online and be sure to check out diykoi pond training resources. There are quite a few things needed to sustain a habitable pond.  When it comes to pond size, bigger is always better. Koi have a habit of growing rather fast, so you have to consider pond size at the same time you are considering how many Koi you are going to put it in.

Your filtration system is extremely important. There are 2 types of filtration, mechanical and biological. Mechanical filtration relives the pond of solids such as dead algae, insects, and Koi wastes. It is important to have enough filtration to sustain the size of the pond, and the amount and size of your Koi. Biological filtration causes a nitrogen cycle, which is what removes dissolved wastes from your pond. Without biological filtration, built up waste will turn into ammonia and kill your Koi within just a few days. Besides the technical aspects of your pond, you will also have the ability to create a visually appealing area as well. Waterfalls, fountains, and other water features will not only add a visual show to your pond, but it will also create movement and sound. A variety of plants and flowers are also available for your pond.
