Bio Media Plus is designed to be slightly buoyant and move freely or remain static (still) in your filter.  The bio-media provides the maximum surface area necessary to allow beneficial bacteria to colonize (grow) and remove ammonia and nitrites from your water.  Removing ammonia and nitrites from your water is essential for healthy koi (fish).  As the bio-media moves around in the filter chamber the bacteria go to work and start removing the ammonia and nitrites.  When your bacteria mature Bio Media Plus is the perfect and most efficient way to remove ammonia and nitrites.

Bio Media Plus is engineered and designed to provide a place for the bacteria to grow and still be protected while it is moving around in the filter chamber.   While water and air in your filter chamber cause the bio-media to move around, the “old” or “dead” bacteria along with any solid waste to fall off.  This chaotic movement makes the filter media self cleaning.  This will also make room for new bacteria to colonize inside the protected wheel.
