Koi Water Filtration

It is extremely important thing to give Koi the proper filtration in a pond environment when raising them.  Koi fish need more consideration when it comes to some of the equipment such as filters since they are more sensitive to the quality of the water then other fish

A pond filter helps to control the biological balance in the pond system and removes the waste that the Koi produce.  In the wild, fish waste is removed by the water’s current and because of the volume of the water in the area.  When fish are in a contained environment they need to have this natural function supplied for them which becomes the job of the filter.  Most of the pond filters that are available have a mechanical and biological function.  The mechanical function cleans particles from the water and the gravity and the flow of the water drag the solid waste out of the Koi’s pond water.  These particles become trapped in the filter and are cleaned out by the pond owner during the regular maintenance of the pond.  The biological filtration relies on bacteria to break down toxic waste, also known as ammonia or pH, into less harmful substances like nitrates which are harmful to Koi in large amounts.  It is normal to have continuous amounts of pH on a low level but it can be harmful to Koi if it is left untreated at a high level.  

Without a pump to force the water through it, a good pond filter may still not work properly.  The strength of the filter may not be able to circulate the water on its own in a big area like a pond so the pump pushes the water and circulates it through the pond. 

Pond owners may want to consider adding a small fountain, a waterfall or some other water device in addition to the pump and the filter.  Having a constant supply of oxygen in the water is very important to the fish to.  Because a fountain or a waterfall stirs up the water, it allows for aeration, which is the process where the oxygen from the air is folded into the water. 

It is important to keep the chemical mixture in the water at a normal and healthy range for Koi fish and this can be done by testing the water. Testing the chemical make up of the water of the pond should be done weekly and this can be done in two ways. You can bring a sample of the pond water to a local pet store to have it tested or you can purchase a home-testing kit so you can test the water yourself. 

Although the time and effort it takes to maintain the pond is minimal, owning a beautiful Koi garden does not mean that it is completely maintenance free.  You should consider the responsibility of owning a Koi garden as it is one of the most rewarding hobbies that anyone can have.

Why would Koi pond water turn red?

when i woke up this morning my father told me that the water in my Koi pond located in my backyard was basically the color red so he had to clean it out. also one of the fish’s in my pond died. i figured this was because of the state the water was in.



I’ve been running koi in my backyard pond for over 8 years, and the only time I have ever had red water is when there was blood in it. Sometimes this is due to one of the fish being injured (usually by raccoons) but some male fish and big (over 20″) females also tend to do it when they are stressed by being moved or handled, or when breeding season is near….

Actually, this time of year (in the northern hemisphere, at least), I’d be more likely to suspect tannins leaching into the water, from all the falling leaves. Is it possible some leaves may have gotten into your pond? The pond water can leach tannins and other compounds out of the leaves as they decompose, and they can turn your water kind of a brownish or orange-y color. Anyway, just a suggestion….

Hope this helps.
