Premium 10″x 18″ 200 Micron Filter Sock

Our 10″ x 18″ premium filter sock has 4 to 5 times more filtration capacity than the typical 4″ x 14″ sock, allowing longer periods between cleaning and changing them out. Water is forced through the widely-compatible 4″ collar of the sock rather than overflowing through the outlet spot, resulting in superior filtration for your aquarium.
