Yes, I replaced the big power hog pump the setup came with. In it's place is the XP3.
I don't have any good pics but it's setup with the pickup for the XP3 at the bottom of the sump and the return just like it normally would be in the tank. It just sits next to the sump. The tank has two overflows which flow over 12 media trays in the sump before hitting the actual water then it gets recycled back up via the XP3.
