AquaOne Filter Sock for ReefSys 180/255/326 Media Bag Spare

The Aqua One Filter Sock is a mechanical prefilter designed for ReefSys aquariums 180, 255 and 326, helping to trap fine particles from the feed pipe before they settle in the sump or return to the aquarium. This supports healthier aquatic conditions, reduces sump detritus and improves water clarity and quality. For maintenance, remove and rinse the sock in clean tap water, turn it inside out to flush out debris and replace it every few months. It is suitable as a replacement filter sock for Aqua One ReefSys 180, ReefSys 255 and ReefSys 326, and can also be used as a replacement for the Aqua One Filter Sock with Mounting Bracket if needed.
