A quick google check makes me think you'd be ok.
"Underwater aquarium filter, suitable for goldfish, Tropical and Marine fish aquariums. For tank size up to: 4ft (120cm) Recommended for biological and mechanical filtration of aquariums from 130 - 215L Fluval 4 plus aquarium filters simple, quiet, efficient, for powerful economy aquarium filtration.
New Clogging indicator, see at a glance when filter maintenance is required."
As this is a UK site, a little conversion is required: at the higher end (215L) is just over 47 UK gallons ~ 56 US Gallon
Good reviews all round!
I have a fluval filter and I have no complaints so far. (mine is an external
canister filter though; 305 I believe)
