Ok, so in post #3 of this thread, in my pictures you can see my frag rack and kinda see one of the baffles on the left side. Now that's an old picture that if still set up like this would fall inline with your comment. I have, since that picture, moved the rock in the back away from the left baffle and now the frag rack runs parallel to the baffle so that all the water coming over said baffle also goes over the frag rack providing additional drag. They both really get the same water flow. SMH, I don't know lol, it's probably just the universal reefer law ; What works for everyone might not work for me and what always works for me might not work for some of you. Crazy, right?
