I've got a few IBC aquaponics tanks set up which is not what I think you want. But I'm in the middle of a project to make one into a tank. I don't have pictures of the setup yet, since it's in process. I'm basing the design in principle off of larger aquarium I have. I did a quick cad drawing to show my plan...
My plan is to use an IBC, and a 55 gallon plastic barrel cut in half to serve the biological and solid filtering. If you look at the CAD "sketches," the inside of the IBC has a drain (

Like I said, this is in progress, but I can update once I get further. The barrels will hopefully add another 40 gallons or so of capacity to the system, so assuming the IBC has 200 gallons, I'm at close to 250 gallons of water. Personally, I wish I hadn't already cut the top off the IBC because I'd only cut a portion off so I had some protection in back for fish jumping out.
