So the overflow box would normally hang on like an inside corner of the tank? The 90 gallon i was originally thinking about getting dedicated the entire back left side for this over flow box and i didnt love the look of it especially since most people coming into the house would see that black box first. The 125 gallon im currently thinking about buying doesnt have anything of this nature. The LFS said they can special order it so they drill holes in the bottom of the tank to the sump so its completely out of site however it was mentioned that if the power fails the water will drain. Sound right to you? Thats probably my best option but i dont like the fact that a power outage could ruin my whole setup.
Overflow boxes usually hang on the back yes, I don't like them very much because they can fail and have to be manually restarted. I trust gravity much more. If you were to drill holes in the bottom and just leave them, yes gravity would drain it, which is bad. But if you get those overflows, the big black boxes, it hides the plumbing behind there which only lets the water drain to a certain point. They seem nasty at first, but honestly if you throw a black background there or just let the coraline algae grow over it, you'll never notice it. If I were you, someone makes 125s with dual corner overflows which are nice, or custom make a small overflow box. I can draw something up if you need.
