The SUNSUN CBF-350 koi pond filter system is a complete box filtration system designed to run pond water through a variety of filter media and fine and coarse foams to keep your pond looking clear. 

 The filter system uses a variety of filter media distributed amongst the different compartments inside its filter bay, allowing you to filter high volumes of water. This single-bay filter system has two (2) blue coarse filter foams and two (2) yellow fine filter foams included.

The filter has four different stages of filtration: 1) firstly, the water passes through the filter media bay (stocked with media of your choice); 2) then the water is guided through a high-quality Japanese mat; 3) after the mat, the water will flow through the filter foams provided; 4) the last section of the filter bay has additional room for filter media.
