I just got back from the aquarium store. They had the parts kit for the Fluval 404 including 3 bags of bio-media and 3 bags of charcoal and ALL of the parts except the container. It was all dusty on a back shelf in a beat up box. I have a 404 that I tossed all the parts last year because they were so nasty. It had no price or barcode and the manager wasn't there to approve any deal so I offered him $20 and he accepted. Is this a good deal? I figured the bio-media and charcoal was almost worth the $20. I'm happy in any case since I can now use the 404 filter. :headbang2:
