What size return line should I run

[Niners4952]

Do I put the valve in the return line to the tank or the line going to the first barrel

Yeah the valve adjusts how much you send to back through your filter. The return line to the tank is unimpeded. The amount of water going back in to your tank is controlled by how much you divert back to the filter.
