Placement is driving me crazy!

[Reggae Fish]

Have a standard 120g (4 ft.)

I have 2- 6000's and 1- 6060

I don't have them on a controller yet. I've tried a million different combos of flow and still getting dead spots mainly in the back between the 2 overflows and in each corner. Can someone please post pics of their 120 or give me some advice on where you would place the 3 and how far down the tank side.

Thanks,
Justin

The controller will help alot by changing up the flow and increasing turbulence.

I know but I'm not going to a controller yet.
