I have a fw tank with my 2 angels with the eclipse hood.  Mind you I have cut out all of the filter unit's and use an eheim cannister 
  
 
Ok little units.  If your going to do a short tank like 20ish inches than it should suffice for what you want to do with it. 
I wouldn't use their filter cartridges though.  Just throw some bio spheres in there and use the bio wheel and you should be good.
