Okay well just for future reference, might wanna state that in your original post just to avoid any confusion.
If you're just planning right now, id plan to have a sump. Plenty of Live rock in the 55, few pieces in the sump and a few powerheads like I said.
If you choose to go sumpless, I can't really help ya, don't know anything about using filters for saltwater unless its a nano tank which a 55g isn't.
