K1 Moving Bed Bio Filter Media is a highly efficient biological filtration solution designed for moving bed filtration systems in ponds, aquariums, and aquaponic environments. Each piece of media is engineered to tumble freely in water, continuously exposing its surface area to oxygen and organic waste while allowing beneficial nitrifying bacteria to thrive.
With a total surface area of approximately 950 m²/m³ and about 500 m²/m³ of protected surface area, K1 media provides an ideal environment for beneficial bacteria colonies. Its unique internal structure protects these colonies from harsh water flow and cleaning cycles while maintaining excellent biological performance.
The self-cleaning design allows the media to remain in constant motion, naturally removing excess biofilm and preventing clogging or channeling commonly seen with traditional static filter media. This results in reliable, low-maintenance filtration that supports stable water quality and improved fish health.
By promoting a stable biofilm environment rich in oxygen, K1 media helps reduce harmful ammonia and nitrite levels while supporting a healthier aquatic ecosystem. It is commonly used in koi pond filtration systems, aquariums, aquaponics systems, and commercial water treatment setups.
Sized at approximately 10.5 mm × 8 mm, K1 moving bed media integrates easily into both DIY and commercial filtration systems and is available in 1, 2, and 3 cubic foot options to suit a wide range of biological filtration needs.
