Loc-Line 3/4" modular hose snaps together one segment at a time, so you can build return lines, spray bars and closed-loop outlets in exactly the shape your tank needs.

Each segment bends and holds its position. That lets you aim flow precisely and readjust it whenever your aquascape changes, with no cutting or gluing. The 3/4" system is the right choice for higher-flow returns on larger aquariums and sumps.
