One thing I wish I would have done is to add a second baffle after the bubble trap. I have the same exact setup as you, 20g display, 10g sump, SS65 skimmer, 130PC lighting, and I wish i would have made my baffle that same height as the first one. So you have your first baffle that goes from the bottom up and then the one that goes from the top down, and then now add one that goes from the bottom up to the same height as the very first one. I know it probably sounds kinda confusing. . . This will prevent the water from flowing harsh over the first baffle and just dragging the bubbles up under the bubble trap. Just my two cents, tank looks great though.
