Sump design critique

[intarsiabox]

It may just be the way the picture looks but the single baffle between your refugium and return section looks to be as tall or taller than the center baffle of your sump section. You would not want it any higher than your 1st and 3rd baffle of your skimmer section otherwise the water level would be higher than your bubble trap and the micro bubbles produced in your sump section will just flow directly to your return section and into your tank. Otherwise the design looks just fine.
