I bought an aquarium out of the paper today and it has a hang on wet/dry filter. It is made by Summit Aquatics. On the left side it has a Hagen 802 attached to a 1/2" pvc. In the middle it has a place for bio balls or what ever. The next chamber it has a 1/2" flex hose mounted near the top drilled through the filter. Then it has a space for media on the end. It also had a clear pvc like pipe shaped like a U with it, and it has a small box that sits inside the tank. Question is how do I get this thing to work? The lady I bought it from had no idea ( her husband set it up and is out of town) I have fooled with this thing all day any help would be appreciated.
