Steps of pond filtration: Section 1 – Water inlet and sedimentation chamber for large sediment. UVC (sold separately) can prevent bacteria, parasites and algae blooms in ponds. Section 2 – Medium density (green) media prefilters pond water capturing particles for conglomeration, sedimentation. Sections 3 and 4 – High density (blue) and super high density (grey) biofiltraton Section 5 – Super high density PU foam for nitrification, denitrification and buffering of pH and water mineral contents. Section 6 – Outlet chamber for polishing and conditioning pond water.
