Description
xPremium moving bed filtration for water you can trust
KoiMaster Moving Bed Bio Filter Media is a smart, compact solution designed to upgrade filtration across koi ponds, aquariums, aquaculture, and aquaponics systems. Each piece provides ample surface area to host beneficial bacteria, helping to support clear, stable water without excessive maintenance. The 20mm white media is tailored for steady tumbling and efficient contact between water and biofilm, so you can manage expectations with a practical, proven approach to filtration.
The media works as a biological filter by encouraging a healthy biofilm on its surface. As water flows through the moving bed, oxygen and nutrients reach the biofilm, allowing bacteria to break down fish waste more effectively. This process targets compounds that commonly impact water quality, contributing to a balanced environment for fish and plants alike, while remaining flexible enough to adapt to different system sizes and configurations.
