This package has two essential upgrades to the Aqueon Aquarium Water Changer with 25 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 Small Storage Strap you'll be able to store your Water Changer properly, and it won't be a nightmare to untangle the 25 feet of hose. This also comes with a FREE MarineAndReef.com Cleaning Towel!
