BioFalls® (biological filter): Provide surface area for beneficial bacteria to colonize and remove excess nutrients from the water.
Pumps: an efficient circulation system will keep the water moving and provide the necessary oxygen levels for healthy koi fish and plants.
Rocks and gravel: provide tremendous surface area for beneficial bacteria to break down excess nutrients in the water and dissolved organic debris on the pond floor.
