The circular thing is the plate for an under gravel filter designed for bowls. It needs a length of rigid airline tube and a riser tube. Air is pumped into the rigid tube where it then rises up through the riser tube. This draws water up the riser tube which pulls water through the gravel and through the plate.
The air powered corner filter operates the same way as the UG filter mentioned above does, however, instead of gravel, water is drawn through a layer of filter fluff and activated charcoal.

That would make a lot of sense. It also came with two air makers and three coils of really old flexible tubing, so I guess someone just packed "all the fish stuff" up and donated it (I even got the cleaning sponges, no joke haha).
It sounds like then, all the parts for both filters are there. The itsy bitsy motor even still works.
Would the corner filter do the job of filtering the tank you think? Or should I opt for something else?
My dad had said (he pulled from memory) that with the corner one, you don't need to bubble it, since bubbles were a byproduct of the filtering. True or false?
