A Veggie Filter have a beneficial effect on the water conditions in fish tanks. Because Veggie Filter absorb minerals including some metabolic waste products from the water, converting these into plant mass. A veggie filter (natural biofilter) is a separate water feature about 1 to 1 1/2 feet deep that is home to lots of aquatic plants (pond plants) that are deliberately starved of nutrients.In order to survive they absorb the nutrients directly from the pond water. These nutrients (nitrates) are present due to the activities of the Nitrogen Cycle, taking place in the fish pond.
