Choosing The Right Koi Pond Filters

There are a wide variety of commercially available koi pond filters to choose from. Some of them are very basic and only provide one means of filtration.

Others combine more than one or even all three. These are the ideal koi pond filter.

The three types of filtration are mechanical, biological and chemical.

Mechanical filters remove debris and organic waste particles from your pond. The water passes through a sponge or floss type medium which filters out the particles and then passes back into the pond.

Biological filters are the most important of the three and consist of a colony of beneficial bacteria grown on a medium, since it must live on a surface.

Materials that are porous, like sponge or lava rock contain lots of surface area, making them an ideal medium for maximizing the size of your beneficial bacteria colony.

These beneficial bacteria work by breaking down some of the toxic organic waste into less harmful substances.

A chemical filter won’t remove all the pollutants in your koi pond and should always be used in conjunction with another method of filtration.

Carbon is frequently used, and sometimes so are resins. They can remove some of the specific pollutants like phosphate or ammonia.

You want a filter that can keep up with the large amount of waste that koi produce. Additionally, the filter should be easy enough to maintain that you will be willing to do it on a regular basis.

Choosing the right system for your pond can be a difficult decision, especially if you’re on a limited budget.

Just remember that this is the single most important purchase you’re likely to make when building your pond. Any mistake could be quite costly in the long run.

Be sure to research possible koi pond filters thoroughly before deciding which system is best for you!
