6105 problem with placement

[oldiron]

I have 2 x 6105's with the 7095 controller but im having a bit of a problem with flow. I have a right hand corner weir with the return outlet returning the flow along the back wall. I have each 6105 in either corner about 6" below the water suface pointing towards the middle front panel. However no matter were i point them i cant get rid of some surface film that collects on the surface on the left hand side away from the weir. The only way i can see to remove this build up is by having both pumps on 1 side blowing around back towards the weir or am i missing something. I have tryed various settings on the controller but no joy.

I have a very low scape which is stocked mostly sps i would upload a pic but dont no how to ?.

Usually if you get the surface moving a lot, such a film cannot form as it will get mixed in. I would probably aim the pumps upward.
