FilterFalls biomechanical filters remove suspended solids, convert toxic ammonia and nitrites to harmless nitrates and aerate the pond. FilterFalls are designed to be able to expand filter capacity as ponds age and fish grow. Efficient removal of toxins and floating particles from the water column improves water quality and clarity. The oversized chamber contains more media material to start with, it upgrades with additional filtration when needed and offers more choices of optional filtration media.
