This package has two essential upgrades to the Aqueon Aquarium Water Changer with 50 ft Hose, a brass adaptor & a storage strap. The Python 69-HD Brass Adaptor is much more durable than the easily broken plastic adaptor that comes with the Aqueon Water Changer. With the Large Storage Strap you'll be able to store your Water Changer properly, and it won't be a nightmare to untangle the 50 feet of hose.
