Can you put an airstone in a marine tank?
Also are there any advantages to doing so?

You can but you might get salt all over your lights!  A better way to oxygenate the water is to add a skimmer

Agree , airstone will create a bit of a mess on the lights , if you really do want a airstone in the tank then there’s a few that you can actually bury underneath the substrate (so long as it’s not sand) if you go for something small and not to powerful then you should be ok but as ajm mentioned better of with a skimmer ,
Back in the day we used to put a drip tray across the top of the tank it didn’t matter then , Think you can still get them ,
Showing my age a bit now , lol
But yeah ajm is spot on with the outcome of using a airstone ,
