^^^ Second that! Don't throw them out. Just save them for an emergency.
Here is an idea of my FX5 media:
Bottom tray is filled with Fluval Biomax.
Second tray is filled with Ehiem ProSubstrate.
And top tray is filled with poly fibers.

Just buy a box of bio max, it'll have more surface area then filling the entire fx5 with scrubbies, I'm sure you can afford 12 bucks. When you think you can afford another 12 bucks add another box, repeat this over time until you have two full trays of the biomax.
