Well this is probably a simple question. I aquired a 20 gallon tall from my work, and it came with everything except a whisper bio-foam filter.

It has the filter cartridge ( white filter ) but not the foam. Is this required? My LFS's don't have any instock either and online looks like my only source at the moment if this item is required.
What benefits does it give if its not needed? My other 20 gallons have them, because they came with the kit filters. It just looks like it gives the bacteria something to colonize on..?
