The baffle on the protein skimmer side could be taken out. And you could space out the gap between the remaining two, also the baffle on the return side should be lowered to reduce any waterfall action. The way it is now, any micro bubbles from skimmer will of course go to the top,but since that first baffles lower it's just channeling bubbles through your baffles. And if you've got a strong pump on return, it's definitely sucking those bubbles like a vacuum into the tank.
