looks good. you should of taken out that very first panel on the left side (closest to the skimmer) and it would of done the same thing and any trapped debris on the bottom of the first chamber would get sucked up and over into the second one under enough flow. now anything heavier will just stay at the bottom of the sump, this would of given you an inch or more to the middle chamber as well.

everything looks great though! cant wait until you are done with the stand!
