Mel and Al - that is exactly what came with my "starter Kit" aquarium.
The bio cartidge has carbon in it so I will not use that unless I need to remove medication. It came with a thin piece of filter floss and then I bought a small Bio filter pad. Both of which I put it my sump to seed with bacteria. In 4-6 weeks they should be sufficiently colonized with bacteria to get the QT running.
This is the simple sponge filter Like what Leebca talks about in her quarantine article
Foam Aquarium Filters: Oxygen Plus Bio-Filter 2
Add and air pump and air hose and you have your sponge filter.
