If you have any questions, please feel free to contact us.\n\nLife Bio Fil is a natural biological filter material. Thanks to carefully selected bacterial strains, it initiates and supports the nitrification process, which accelerates ripening. Life Bio Fil is the perfect filter material for newly installed pools. Life Bio Fil also increases the efficiency of filtration in older, already functioning pools. Thanks to its bacterial content, the nitrification process begins almost immediately - there is no need to wait for the medium to colonize. Life Bio Fil should be placed in the sump when the water flow is good. 1000 ml of medium should be used in an aquarium with a capacity of 400 l. We recommend replacing 10-20% of the filling every 6 weeks.\n\nCancellation policy\n\nRight of withdrawal\n\nYou have the right to cancel tht
