Love the sump David, I really like the settlement chamber awesomeIt depends what you're trying to achieve. My sump has baffles as I wanted to create a settling area for the heavier waste produced by my Panaques, and because I used Poret foam for my mechanical media as I wanted something that was going to last longer between cleans than filter socks. Ideally I'd run a pair of 50 micron socks after the foam as it still lets through some of the finer particles (finest sponge is 30ppi) and I've noticed a bit of a build up in my matrix, but at 2.2M long already I didn't have the room to extend it further to incorporate the socks! I could run the socks where the matrix is then put the matrix in bags in the last compartment, or the other option I'm considering is replacing the matrix with something like K1 that is self-cleaning.
I really like the no-baffles set up, and if I were doing a sump for a smaller tank, or with different stock (no wood-eating catfish!) then I would happily go down that route.
