Do you have a preference? if not then the advice will be all over the place. Otherwise just go with the Fluval Fx5 (canister) -see the other threads as to why
Eheim Pro 3 (use an additional layer of filter floss) or Eheim 2250. If heavily stocked: Eheim 2260.
To use Ducati's words: -see the other threads as to why
There have been threads on these filters as well as on longest-lived equipment (use search option). All in all, Eheim provides good filtration, high reliability, and best longevity and thus best value for your money of you plan on keeping the tank for a while. The FX-5 seems to be a decent filter, however, its long-term reliability still has to be determined.
If you ask 10 people about the kind of filter to use , youll get at least 5 different answers. I have a 180 with an Amiracle wet/dry on it. Its been running for 8 yrs without any problems. The pump is a Little Giant 1200 gph. A lot of what kind of filter to use is answered by what kind of fish you put in the tank.
