I've Had RBP before, about 10 of them. in a 55.
IMO, Your better off getting a Canister Filter that will have a good amount of water being cleaned.
If your feeding live (which is what i did) it's gonna get messy and the water will foul with HOB filters.
AT the time i HAD 2 Huge Whisper HOB filters and had to clean them out all the time.
Water was always cloudy and the Substrate always Dirty with fish remains and Feces.
Just IMO tho.
Good Luck
