Well, the shrimp showed up... they hadn't yet by bedtime but they're in there as of this morning.
Today we get all the 'under the tank' stuff hooked up & operational. Everything works, and not a SINGLE leak in the plumbing! Just our Coralife Stupid-Skimmer we're having trouble with, but a new skimmer is on it's way anyhow so I'm not too worried.
The new returns don't skim the surface of the water, and while there appears to be lots of flow in the tank, the surface isn't 'choppy' like it was in the other tank. I'm going to mess with the direction of the powerheads this evening and see if I can get them just right.
I'll post some pics this evening, once the water clears a little from today's excitement - the refugium created quite the sand storm when we first fired up the pumps.
