Well I finally finished my sump for my 40breeder. It's a glass 29 gallon with HD acrylic baffles. The main dividers are 1/4" and the three baffles are 1/8". The baffles are spaces 2" apart and are 12" tall. The only thing I haven't decided is whether I will run the return pump externally or submersed.
