Advanced Return line kits, will include a back flush siphon break feature designed to disrupt a reverse siphon, preventing excess water from back flushing into your sump in the event of a power failure. This feature allows you to extend the return line deeper into the aquarium providing better water circulation in hard to reach areas without using additional power heads. This feature is also adjustable to re-direct back  pressure into the aquarium preventing misdirected back spray inside the aquarium hood.
