## Description

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 crystal clear. This system is suitable for ponds with fish up to 1, 500 gallons or ornamental ponds up to 3, 000 gallons. Filter operation the filtration 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 high-quality Japanese matting, 3) after matting, the water will flow through the filter foams provided, 4) the last section of the filter bay has additional room for filter media.

Review: Great filter - I own two of these. I bought one a few years ago that is still working great and bought this one for a second pond. Keeps my pond crystal clear and I only have to clean it once a year.
Review: Works better than expected by a long shot - Pretty straight forward as far as setup went. Now to be honest this is not my first rodeo so I am speaking to the more experienced Koi pond owners. I've got a small 850 gallon outdoor Koi pond with approximately 50 different sizes of fish, along with snails and of course frogs. I do use water hyacinth, and submerged plants also. I've been using a Tetra pressure filter for the last couple of years with decent results ( just did more frequent exchanges with less volume). This year though with the tremendous amount of rain and temps being all over I couldn't get it under control without possibly going the chemical route. Anyways making this boring ass long story short I did due diligence and research and decided to try this first before the chemical route. 24 folks....24 hours, that's how long it took for the pond to go from the smelly swamp ass to actually something pleasing to be around. Now I'm sure cleaning the filters will be nothing to celebrate (actually it's a great design, pull them out, hose them off, slide them back) but with the job it's done so far it's amazing.

Make sure you read how much the filter can handle. Mine overflowed because of an overpowered pump. If the pump flow is too much it will spill out!
