First chamber you want the the overflow going into. You make 8- 9 inch baffle and room for your skimmer.

I did a bubble trap baffle and then to my return section.
The last section is where you height varies and you setup your ATO and return pump.

I bought a marine bio systems kit for my 20L off ebay. You can see how the baffles are laid out.

You should fine some commercial sumps online that are the same approximate size and see how they're laid out and organized.
