Need some sump advice, will this work??

It will work. But everybody allways forgets mechanical filtration before the refugium. I would add at least 1 more baffle to the input side and separate by 1 inch.

Fill that baffle with as much LR rubble as you can.

You can also get a sock but you have to worry about the skimmer pump pulling on the sock. Turn the pump around and you can use a sock.

Socks can become a problem because you are constantly running sw over bad stuff.

I understand the placement of the skimmer. They take a big footprint. But you want to clean as much as you can before the refugium.

Just my hillbilly thoughts.
