An Emperor 400 and an Emperor 280 would do great. I used to run an Emperor 400 and 280 on 75 gal and they provided plenty of water movement and the already mentioned biological and mechanical filtration. Also ran two Emperor400"s on eighty gal Discus tank but am expierimentingwith sponge filters . I now use one Emperor 400 on both the 75 gal and eighty gal discus tank along with two sponge filters in each. Not as much current ,although None of the fish in either tank seemed to mind.
An emperor 400 and 280 on 55 gal will do well. (PS) I very much like the sponge filters for their simplicity, but Properly sized sponge filters take up considerable room in each corner of my tanks and bristlenose ,along with White spot pleco are nibbling little holes in them
They also affect the aesthetics. I may go back to the two Emperors at some point.
