If I go with another Eheim 4+ 600 canister should I run the flow in the opposite direction to the first one or in the same direction?

I run my two canisters pointing forward and down the glass, then the intakes pull the water back across the substrate. So there is a circulation loop on each side of the tank.

I'm not sure I understand what you are saying. Could you elaborate?

Water return is at the surface. Mine point from the back of the tank to the front.

My filters are placed at 25% and 75% positions along the length of the tank.

i run a 600 and a 350 on my tank. I did have have the flow running from the back to the front but now have it going along the tank. I also have a power hear which I use to increase surface water movement. i have one spray bar pointing along the top then on the other side its 45deg down. I found since changing to this set up the fish are a bit more active especially my Fryeri who will swim along the current on the top and when he reaches the other side catches the current along the bottom going back. he will spend most of the evening doing lengths of the tank

75 gallon? Haps? Number of total fish inches in tank?

Don't go by inches. The inch/gallon rule only works with skinny one inch fish like neons.
