Best Position For Maximum Circulation

[catterbury]

Hey all, just wondered, what is the best position for the inlet and the outlet of a canister filter on a tank? I have the Rio 240 without the internal filter and currently have the inlet coming through the gap on the left hand side of the tank, and the outlet on the right hand with the 'nozzle' pointing sort of towards the front left corner of the tank. I dont think i am getting a good circulation with this though as the flow doesn't go around the back and to the right hand side of the tank. I have a spray bar too if any suggestions on using this instead? Using a fluval 405. Many thanks!

Mine goes from right/bottom to left/top - both pipes are at the rear, the return is about 6 inches from the rear glass... in a 4' tank, there are a couple of "dead" spots, but i doubt you will ever get 100% circulation without power heads...
