Life Bio Fil is a natural biological filter medium. Selected bacterial strains support the nitrification process and work immediately. The insert is an excellent filtration medium for newly established aquariums and also increases the efficiency of filtration in functioning tanks.
Life Bio Fil should be placed in a sump with good water flow. 1000 ml medium should be used in a 400L aquarium. Every 6 weeks we recommend replacing the 10% -20% refill.
