The filter is of utmost importance in keeping your Koi pond crystal-clear and free of chemical pollutants. Our line of filters are designed to meet a wide range of needs, for both large and small ponds.

Mechanical Filtration: Refers to the physical removal of debris from water by materials that trap large and small particles. Koi ponds traditionally use some form of solids separation, either passive (vortex chambers) or mechanical (micron-screen/static K1 separators).

Biological Filtration: This is where your pond filter provides a home for beneficial bacteria to grow on special media. These bacteria remove harmful pollutants from pond water. Known as the "Biological Filter" these beneficial bacteria convert poisonous compounds such as ammonia and nitrite, into less toxic nitrate. The end by-product, nitrate, is used as a food source by aquatic plants. This continuous process is called the nitrogen cycle.

It is important to think of your filtration in terms of a "system", where components are carefully selected and matched to provide optimum performance, ease of maintenance, and cost effectiveness (both initial and long term operating costs). These components must perform 3 basic functions;

• Removal of waste products from the pond
• Separation of solid waste
• Conversion of soluble waste

Kindai Koi offer a range of proven and effective systems that will provide enduring and effective filtration solutions. We have extensive experience in the design of filtration systems, and offer free design services. Please feel free to contact us should you require any guidance with your project.
