When you have a Koi garden or pond, it is important that it stays clean and the best way to do that is by using a Koi filter. But there are various types of filters that you can purchase, so it is very important that you understand what is available. Having the right filter means that you will have a system that works for you when it comes to your budget and the size of your pond.

The filter you want to look at is the biological filter. This is a filter that is made to get rid of particulate and organic substances. These filters use what is called anaerobic bacteria-laden filter media. A biological filter breaks down the harmful substances that can damage your fish and your pond. It removes decaying pond creatures, fish waste, leaves, and other decaying debris that sits at the bottom of the pond.

Bacteria is used in the breakdown process because it is a special bacteria that can take substances that are harmful and break them down into something that is not as harmful. For example, ammonia is broken down in two stages. Each stage also involves a different type of bacteria. The first stage is the nitrifying of the bacteria and the second stage involves converting the nitrite to nitrate.

If you have been thinking about a Koi pond but are afraid it may be too difficult to consider, think again it really is not as difficult as you think. A Koi pond can be a beautiful enhancement to your garden and if you build and maintain it properly you will have a pond to be proud of for many years.

Choose an area where you can build a pond large enough to allow your fish to reproduce ant grow in size. They like elbow room so be sure you have plenty of room for them to swim easily. It is not a good idea to have the fish so crowded that they are bumping into each other at every turn. Of course you will want to be sure that you do not have more room than you need. Filtering the water and adding medication if you need it can be very expensive, especially if you are working with more water than you actually need.
