i'd go with (2) canister filters. either rena xp3's, eheim 2075's or if you want to drop some major cash and go overkill 2 ehiem 2080 or 2180's with the internal heater, but you will have enough filtration for upto a 640 gallon tank
you can never have too much filtration, unless your fish are getting either sucked into the intake tube or either being blow into the glass lol
