Hey Guys! Long time since I last posted. I'm custom building a new AIO aquarium, and I will be lasercutting the back wall. I will have the design made by the cutters, but I need to tell them how high and how tick and how apart should the "comb" of the backwall be. I will make it like the Nuvo 20, with one comb on each side of the back wall. Please help as its the first time I'm having a AIO made and I want to get it right the first time. Thanks a lot!!
