The main trend with SW tanks (fish only or reef) are to use Live rock for the filter.
If you do this most people will not use bioballs or other such stuff... though many still will trap the big pieces of poo in a filter and clean that as often as possible.. most dont even do this.
the SKIMMER is the seccond most importiant thing in this set up... it will mix all the water up, add air and pull out the ,,,well, protien.
Live rock.. yes you can get dead rock.. the more porus and less absorband the rock the better.
Live rock just means that it is from the ocean... it would be like if stores sold dirty filters and called them "live" filters.
In the same way that you can take a new filter, put it in an old running tank, then put it in your new tank with all the great bacteria.. you can seed dead rock with a few pieces of live rock.
I haven't really found a great deal on dead rock... I got some live rock when I first started... I am sure I will want more but I plan on trying to make some in the summer (I live in an apartment style condo... need to wait till I can drive over to my folks' and use their yard hehe).
It is best to get all your live/dead rock at once. The Live rock takes a while to cycle because there is lots of dead stuff in it.... the bacteria must eat it then die, then other bacteria eats that and dies... untill balance is found. besides it is fun to see all the different shrimps and worms and stuff come out of the rock... (latter your fish will eat them all probably hehe.
You also need to take the time to try to find BAD CRABS!!! mine got some fish before I found them
they call them hitchhickers.
If you get Live sand that will help too
If you are going Fish only tank, you can use the same methods as the FW tanks. if you wish to stick with what you know.
Oh right your question... No, live rock makes it easier to maintain
