I am going to be hooking a frag tank inline with my display tank becuase I want the water params to match in each tank and I did not want to buy hardware. This is my idea, see screenshot. Where the frag tank is really the only place to put it since the DT is in the kitchen and livingroom in between the back sliding door and the window you see. So I was thinking of just letting gravity bring the water back to the SUMP in the DT and a MAg12 sending water to the frag tank. There wont be much head loss.
