here's how it was explained to me.
airstone releases extra air into the water and those bubbles raise to between the water and the hood.
this oxygen above the water displaces the carbon dioxide above the water forcing it back into the water. once back in the water, the co2 causes the pH in the tank to crash.
Also with salt creep, the salt rises with the condensation into the hood, the water drips back into the tank leaving the salt and your salinity crashes.
so I would say NO to anything bubbles.
Reefers are always trying to keep the bubbles from skimmers and refuges out of the tank, no reason to go against their experience and add them i think.
Also, I would think that with the amount of current you should be running these bubbles are not going to create a wall, they are going to fly all over the tank, getting stuck under rocks and creating nitrogen air pockets so that if you move the rock, the tank crashes.
