I painted background black and finished plumbing the return and drain to basement sump
Here are some pictures and video of my dual refugium / sump with DSB, Cheato & auto top-off.

I have since replaced the skimmer. I purchased a Bubble Magus NAC7 because my Vertex in-180 was too much of a tight fit. In fact, I initially was going to put the skimmer in the same chamber as my return but I calculated my height wrong, I needed an extra 4 inches. The second sump was a tad lower but I still would not have enough height to raise it to the recommended water level. Rather than re-building the stand, I bought a shorter skimmer.
The cheato is now in the last chamber right before the return pump.
I will be posting the rest tomorrow. Thanks for looking!
