I have a Mag 5 return pump. What size I.D. tubing should I use for the most flow? I was thinking of connecting to flexible pvc (spaflex) at the tank egdge. I want a U-tube shape so I can snake a hose brush thru. I currently have hard-plumbed pvc 1/2-inch. I don't think I can get the hose cleaner through.
