I just bought a 40BR for my sump from Petco. Great timing as the truck just pulled in with one and it was the only one they had. Next question is since I have a refugium I am going to use. Do I need to put baffles in my sump. My plan was just to put most the mechanical stuff there, heaters, dosers, ato, etc. and some live rock, no lighting. Also, where is a good place in Buffalo to get a hole cut into the breeder? How expensive will it be? and how big should I make it?
