Here's an updated picture of the sump in the RSM stand. I shortened the lines so get rid of some clutter. The ATO float is in the back left corner and the skimmer is a HOT hanging behind the cabinet. I didn't have enough height in the stand to put the skimmer inside the sump. The reason for so many lines in the sump is it feeds and returns from three tanks, has an ATO line and there is a skimmer supply and return.
Here's the skimmer and Phosban Reactor (filled with Zeovit and carbon).
