As you can see, towels are always handy to soak up excess water. The old sump held 37g to the top, and had to be run rather low to avoid a mess when the main pump is off. Prior to the installation of the new sumps, the plumbing was redone, and an electrician installed the sub-panel on the left.

The new sump incorporates a separate refugium. The sump holds 57g to the top; the refugium 20g.

The main drainline is divided with two drains. The 2" drain pours into the sump's skimmer section. That section also houses 2 Ebo Jager heaters. The skimmer is a Tunze Automatic Skimmer 240/3. It is sitting on a 6" stand. The refugium drains via two parallel 1" pipes into the bubble trap, which pours into the return section.

The bubble trap has a tray incorporated to run carbon when desired. The tray holds pH and ORB probes nicely.
Dimensions: 36" x 23" x 16"

The refugium is on its own stand. A Dolphin Ampmaster 3000 is located beneath the stand.
Dimensions: 20" x 20" x 14"

All the refugium needed was 20g of saltwater, which wasn't ready when I took this picture. Lighted with a 28w (output 200w) CF floodlight, macro algae should have no problems growing in this predatory-free environment. A ballvalve is visible above the bowl filled with caulerpa, and once opened will provide source water.
