Update -- mid cycle.
Tank is up and running. Big shout out to Mike (
@Coral reefer) for getting this plumbed. What I thought would be tons of interior cabinet space turned out to be a tightly fit jigsaw puzzle with the chosen equipment. Beyond the large sump, large skimmer and ATO reservoir you quickly run out of room when you're also plumbing in an 80w UV sterilizer, a 40w UV sterilizer, an Alge Scrubber, etc. We ended up suspending the 80w above the sump and having to push back the sump etc to install the 40w in front.
The four Orphek Atlantiks were very challenging to mount as well. Orphek doesn't make a mounting solution for a Euro-braced tank and hanging them was out of the question because of a 16' slanted ceiling. I ended up using two Ecotech RMS bars and hanging them on that. It has some bow in the middle, but I'll fix that shortly by strapping some flat steel"beams to them.
I ended up removing some of the rock as it was just too much. Now it has more open space and looks even more "shelvy."
Electric is all run and everything is working. I still need to do some cable management, but it'll never be as clean as I want it. Just not a talent I have.
Cycle is about a week away from adding fish and some corals.
