Alot of it does go over the top, so 3 baffles would mean the baffle just before the refuge makes the water go under and you would get better circulation. Alot of mine goes over the top, but it does mix up some especially since the macroalgae is filled in the fuge even all over the top. I don't get any bubbles into the return area that returns to the tank. The sump design is good, and I am sure there are better ones out there.
