When I first built my tank I made an overflow box and siliconed it to the back of the tank. Within the box I had made it "silent" by adapting the standard "Beans" system, requiring all the pvc elbows to be in the box within the tank. I now have recently made a upgraded replacement DIY "slim" style overflow box which "requires" another outside box. After planing, cutting, glueing and building both boxes, I was talking to a friend and he told me that if I were to switch to the new style inside box that I would not have to use the outside box. Seeing how I already have my gravity, full-siphon and fail-safe drained already mounted to the bulkheads. Input? As you can see, it has been inspected as well.
