A filter sock is a highly effective form of mechanical filtration and will remove particulates and debris before it is broken down into nitrate and phosphate in your aquarium.

The Eshopps Cliff Hanger is one of the easiest ways to quickly add a filter sock into your existing sump or aquarium. Use the Cliff Hanger with a standard aquarium to create a DIY sump, complete with mechanical filtration and bulkhead connections for your drain pipe(s). The design also integrates a small drain chamber to diffuse water and quiet things down as the water enters your sump.  

This clever bracket comes in two sizes which gives you the option between a standard 4" round filter sock with a single drain connection or a larger 7" rectangular filter sock with two drain connections.  If filter socks are not your idea of fun, the Cliff Hanger R is also compatible with the Eshopps Bio Cup R filter media cup.
