matt, I understand what Reef Ready means. I was asking for frogguy1 benefit. I'm very satisfied with my Oceanic Reef Ready tank. When I ordered it I had the option to put the overflow box anywhere in the tank. I picked left of center. I could have had Right, Left, Center, or both corners. I also believe turbulence is a good thing in a tank. My water drops 5” in the overflow, then down to the sump where I have a flex tube that curves around. The new overflows also have vents at the top, middle, and bottom that cause circulation down the length of the overflow box, eliminating that “Dead Zone”.

The only thing I don't like about overflows is the wasted space in the tank. But I hate stuff hanging in or on my tank even more.

frogguy1, Make sure you get a big enough sump for your tank and make sure which ever way you go your input method and sump can handle power outages without any issues.
