CADE High Flow Filter Sock 4", Altumate S1 and Reef S2

CADE Reef 4 inch nylon mesh filter socks to suit Altumate S1 and S2 mechanical filter boxes. These also suit Reef S2 models. They are higher flow course grade mesh that only remove larger solids with the advantage of not getting clogged easily. We recommend using one of these with a square floss pad over the top for easy disposal.
