The pond filter is essential for keeping your koi pond water crystal clear and free of pollutants. Our line of filters is designed for both large and small ponds and provides two types of filtration:
Mechanical Filtration: Refers to the physical removal of debris from water by materials inside the biological filter that trap large and small particles.
Biological Filtration: A biological pond filter provides a place for beneficial bacteria to grow on special media. These nitrifying 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.
