Which should be first? Media or a Raft??

[David W. Russell]

I just had a thought and need some information.  I am building a fish tank to media bed to a raft bed to a sump tank.  Or should I go from the fish tank to the raft tank to the media bed and then the sump tank?  Has anyone else tryed this layout?  Which would you do?
