I have a custom built skimmer with a 4 inch body 24 inchs tall. I just got a deal on a euro reef which is 6 inchs wide and a lil shorter. My tank in a 90 gallon with a 40 gallon sump. With a small fish load.

What will i gain by going to a wider skimmer?

It all has to do with the contact time the bubbles have with the water. You may get a better cyclone with a wider chamber.
