for your sewtup what are you doing and how many fish, if its not to big then the SWC cone 160 all the way I used this skimmer on a 150 gal with a 40 gal sump andf it was totally bullets all the way. pulled amazing crap out and it has a small footprint, along with super quiet and cheap its like 259 before taxes. 
  
I would take it over all thou skimmers
