Exactly! I have seen pictures of this tank before and it's a "coast to coast" overflow. Basically most of the back panel has cut outs like a typical overflow. This overflow spills into a 5”X5” or so tray box that is attached to the back of the aquarium. This design doesn’t use any aquarium real-estate at all and can move large amounts of water.
Yes it is attached to the back of the tank..The top was welded on then the builder went back and routed (Fluted ) the teeth in without damaging the integrity of the glued top pretty trick !!!!

the filtration after the 190 gallon sump there are two Wlim pumps one directly to an Ultima 4000 the other is just max flow yet to be hooked up a dolphin ampmaster so total flow will be at 9000 GPH......
One more photo side view of overflow maybe will give better idea of how it's workin...By the way tried to rotate the pic but moving it to my computer it just went back so sorry for the crooked necks LOL!!!!
