I guess that's a good loop setup.
BTW, to cut down on price, get 10ft of Clearflex 60 1/2" or MasterKleer 7/16". For $.37/ft, you can't go wrong.
Also, i'd probably just go water and 10% antifreeze with dye for fluid. This is my first WC build, and that was the mix i used. Just make sure to leak test for at least 24 hours
