Yes, get some LR
and Live sand for the tank. Then use the current filter, in conjunction with a couple of well placed powerheads, to create a current. The current will allow the LR
to do the filtration. This is a much more natural system and will actually mean less work for you, because as was mentioned above media in filters tends to lead to high levels of nitrates in saltwater tanks which will kill any inverts and means more frequent water changes.
Plus the LR
will just make your fish more happy and make the tank look much nicer overall.
