filter placement

[mralgae]

hi all,
just a quick observation on filters and there placement and which is the best.
i have a rio240 tank 4ft. external ehiem filter. i have been trying to find the best placemet for the inlet/outlet pipes. given the likes of internal filters have inlet/outlet in the one place i would persume this would be the same for an external for them both to be at the same end of the tank. i have seen some set ups with the inlet at one end and the outlet at the other. does any one know if the pacement, one way or the other has any effect on the filtering system.
in other words is there a right way and a wrong way to have the inlet/outlet?
regards.

I have seen them at both ends of tank and then at the same end of tanks but i would put your inlet outlet pipes at both ends of your tank

thats the way i have them now karen both at one end, just wonderd if there was a right or wrong way. i put them both together as like per jewel & internal filters as if it works for them its got to work. ( but then knowing me anything could happen.................. )
