Got her up and running yesterday. Still a lot of work to do.
I ended up only hooking up one XP4, the flow seems fine and as the wife enjoys the "jungle" look anyway. I believe as was suggested earlier the second one would of been wasted current.
Fish seem very happy, my loaches are incredibly active, it seems like they are reestablishing their pecking order in the new tank.
Please excuse the mess, so many things need cleaned up - I have cords everywhere, suction cups that are not holding things right, plastic that isn't fitting - ahh the joys.
