It provides more water volume(solution to pollution is dilution), a refugium can easily be incorporated into the design providing nutrient removal and a natural food source for fish/coral and more stable PH(pods
, worms, etc breed in the fuge and supply the tank food also LR
can be added here w/out cluttering the display). Also overflows are great at keeping the water surface clean and getting the dirtiest water right to the skimmer, making your skimmer work more efficiently. Hiding equipment and getting some PH's out of the display is the icing on the cake. IME all that HOB
equipment introduces micro-bubbles to the display, which I absolutely hate, as well.
