Aqua One Filter Sock for ReefSys 180/255/326 Media Bag Spare

Aqua One Filter Sock For ReefSys Aquariums180, 255 and 326. The Aqua One Filter Sock acts as a mechanical prefilter for your sump. The Filter Sock will trap fine particles coming from the feed pipe before they settle in the sump, or are reintroduced into the aquarium. This provides healthier aquatic life, reduced sump detritus, improved water clarity and quality. This filter sock is also suitable as a replacement for the Aqua One Filter Sock with Mounting Bracket - it is not the same size/shape but close enough to fit and function as a replacement if necessary.
