When I was doing large batches like this some years back, I had no real 
complications with a large tank.  Gentle inversions at 1 minute 
intervals were part of my normal regimen so that was quite easy to 
accomplish.  I was using FG-7 at 1:15 which gave what I'd term 
"middle-of-the-road" sorts of developing times, I used a pre-soak and 
the only complicated issue for me was the washing.    I had an old 
Wat-Aire (sp?) tube washer that was too short for everything at once, so 
I constructed a PVC tube rig that was featured in a magazine back then.  
It was designed to have a certain size and number of holes drilled in 
the bottom point of the sides to allow a slow flow from the top, out the 
bottom.  You can make the tube as long as you wish, clamp a hose at the 
top and tune the water flow to maintain a constant level.  The tube was 
closed at the bottom with a simple flared cap that was some sort of 
normal plumbing piece.
