Berlin skimmer Mods? Is there any?

[banditpowdercoat]

I'll be running a Berlin "Triple Pass" Skimmer for a while on my 150g tank. It came with the tank, and can't afford a "Nice" one. I will be feeding it with a Mag 7. The air injector, is on the outlet of the pump. I see alot of "mesh Mods" for other pumps. Would putting the air injector before the pump and some kind of mesh on the impeller work better for smaller bubbles?
