I recently watched a video about setting up an external filter which seemed to make a lot of sense. It said that the bottom basket should contain the foam with the finest grade right on the bottom and then the other media baskets should be devoted to ceramic media. They thought that a small amount of media in the very bottom of the cannister would help the larger particles of waste to be left behind in that chamber. This makes sense to me but I feel that surely the filter manufacturers - certainly the big ones like Fluval - would know the best way to set up their filters? I also watched a video about unoxing a new FX6 and that came with the mechanical filtration at the top too.
So what do you all think about this? Do you think it makes much difference? What about the amount of ceramic media that comes with the filters, it never seems very much to me. Is it possible to get a significant improvement out of a filter by making these sorts of changes?
