Welcome to MFK, as far as what filtration you should get, I have no idea sorry...seems like the first two people who posted have some good filters though
Are you new to the hobby, or just looking for suggestions? If you're new to the hobby, I would suggest a couple of HOBs, maybe an AquaClear 70 and an Emperor 400. If you're looking for suggestions and are comfortable going canister, I'd go with that Eheim suggested above or a Rena filstar xp3. The FX5 is great, but may be more flow than you really want in a 75.
