As well, the pond must be kept at a certain temperature - around 59 degrees F. Thus, a heater or de-icer is usually a good idea to keep ice from forming and to assist in the decomposition of organic matter.
An aerator can also be a wise accessory for fish ponds. They provide the pond with oxygen and help with decomposition of organic matter. This process releases the toxic gases that form because of decomposing matter at the bottom of the pond and allows the pond to get the oxygen it needs. A thermometer is another definite necessity for fish ponds.
Be sure to look into the proper nutritional foods that Koi require and what they can and can't eat. Barley straw bales are often a great addition to your pond which will provide your fish with healthy food and help control algae at the same time.
There are many other types of fish suitable for a fish pond like carp, shubunkins, ruyakins, fantails and comets. There are many things to consider when purchasing or breeding fish . It's all about balance. You need to ensure your water, vegetation, bacteria, temperature and many other things are balanced in your fish pond. If you live in a zone where the temperature stays between 55 and 60 degrees, you can almost use any kind of tropical fish.
