Water flow

I have a new 180 and it has only one inflow set up. I want to set up a PC pipe along the back. Is alot of little holes or several big outflows better???

By "inflow" do you mean a return to the tank? I guess the size of the holes are going to depend on the amount of pressure your return pump is pushing out, I think if it has alot of force you would want larger holes but, I would start with smaller to larger holes to keep enough pressure to get to the end of the pvc pipe.

Yeah I mean from the pump to the tank. thans for the advice
