Not speaking from experience BUT

I have an eshopps r200 sump and it has a mesh filter between the

middle chamber where my skimmer is and the chamber where the return pump

is and I was told that it was there to only cut down on micro bubbles.

I am attaching a pic of the sump... You can get pieces of foam mesh like this in

plumbing department perhaps????
