Alternative to foam in refugium chamber
 

So I have the eshopps R - 200 sump/refugium. It came with a foam pad between the refugium and the return pump. It's excellent at reducing micro bubbles but with it there it will reduce the amount of pods returning to the DT. But without it the water tumbles over and creates bubbles which make their way to the DT. Apart from raising the water level in my return chamber of the sump does anybody have a suggestion to reduce bubbles but still allow pods to pass through.

I used filter mesh on the backside so that the water gently flows down the mesh instead of falling and creating bubbles.
