Default Purchased used Eheim filter and have questions


I purchased the following filter second hand:

...and I'm missing the bottom layer of plastic(?) filtration media shaped like cylinders, and the layer of little rock looking things in the layer above that (biological?).

I think I've identified what they are:

Bottom cylinder layer:

Layer above that:

So my questions:

  1. Do I have the right products?
  2. Are there any cheaper alternatives that I can use to replace the official Eheim stuff? (hopefully)
  3. In what amounts should I puchase for my particular filter?
The user manual is quite unhelpful for this matter. It assumed I already have this stuff and doesn't give any details.
