Filter socks are a great way to polish the water and export nutrients at the same time. For best results we do recommend changing out filter socks ever few days, to keep the detritus from breaking down and turning into nitrates. Between filter socks and running a good quality carbon in a reactor crystal clear water is easily obtainable.
Note: Please rinse all filter socks in RO or RO/DI water before use
Filter socks are molded directly to the hanger and are not replaceable.
