Here is my sump.
Far Left - 2.5G ATO reservoir and ready to be installed ATO system.
10G Sump:
First Chamber - Inlet from Display; Tunze Skimmer; MJ400 feeding to Chiller
Second Chamber - Outlet from Chiller; LR; Sand (too much - I guess it's a DSB now); Chaeto; Mangrove; 2 x 18W PC Coralife fixture; Peacock Mantis!
Third Chamber - Return to tank (MJ 600 -- I wanted to use my QuietOne 3000, but this is better for now); future home of ATO switches.
The ugly pink stuff is just some foam for the sake of noise insulation. This tank is next to our bed and I want it quiet. The foam was left over from what was used to put under the display tank.
