I have a 150 show tank non reef ready with a hangon overflow box that has been up and running for a few years. I also have a 120 oceanic show tank that is reef ready with two corner overflow boxes that I have posted for sale on this websight. Both tanks are 48 in wide.What I need to know is it worth it for me to break down the 150 non reef ready tank for the 120 reef ready tank.Here are some pics of tanks the black cabinet is the 150, and the oak cabinet is the 120.
