Thanks!
RR means Reef Ready. An unnecessarily fancy term for a drilled tank.

It will be modded to prevent excape through the overflows.
I am not currently running a reef, but have in the past. I've got a high paying job and want to start up a new tank. I've always wanted to keep an octopus, but was unable to afford the equipment to care for one properly.
I chose a 240 to give the animal a good amount of space, but also to make it a focal piece of my living room. This will include a few corals as well. I think it's time I stepped up from the 10 gallon ranks.
