Alright, so now that I have my 150g setup. I'm working on the sump setup now. I have all the plumbing set, getting ready to put the baffles in place. I'm going with 3 baffles at the inlet side, and 1 baffle for the return side . I've seen so many differing opinions on spacing of the three baffles, as well as the gap at the bottom. Sump is a 55 long.
