So after all that, here's what I ended up with.
I'm having a bit of a conflict with the low rock pile to the right. I really want to turf it but its the only cave structure I have for fish to hide and I think that's pretty important in the long run, so I may have to keep it. And yes, those are SPS pieces that I kept from the 104.72 lagoon. They were crowding the 150g reef so I threw them into the FOWLR.
Here are a few of the inhabitants.
There are a few others but I'll save them for later
This weekend I hope to skin the stand and set up the automatic water change.
