80G fish only filtration advice

[reefer madness]

a friend wants to put an 80G salt fish only in his office. I've been into the reef setups the last 8 years so I'm not sure about the latest in the fish only filter set ups. Excess noise would be a factor in this. Any ideas?

A really quiet wet/dry would also do the trick. The rock and sand would be best of course but the wet dry will also do a good job and also save some money.
