I would not recommend it-think about the ocean-waves are on during night time too. Circulation is especially critical for reef tanks; I keep all my pumps (4 Koralia 2's, 2 Koralia nanos, 1 350gph canister) on 24/7 for my 55 gal reef tank. My understanding about pumping air into SW is that it can be bad for fish, others will chime in about that hopefully.
Just curious-why are you thinking about doing it?
