Just wondering if any of you all have converted a 20 Long into a sump. My main concern is the size of the baffles in width. The dimensions on the tank state 30"Lx13"Wx12"H. I am sure that the internal dimensions are different. If you have built one, what sizes did you use for the baffles? Also, what did you use, acrylic or glass, where did you have the pieces cut?

Thanks,
George
