摘要：
Disclosed are vertical sock filters for aquarium filter assemblies. The sock filters typically include an annular collar coupled to filter material. The filter material typically is a composite material that includes upper material and lower material, where the upper material typically is more porous than the lower material. The assembly and the annular collar may include respective first and second coacting components that mate or interlock with each other.
