Film On Surface Of Water

[jrussuk]

Hi
I have a scubacube 125 ltr tank which has a tetratec ex700 filter with a spray bar which is facing the back of the tank giving me a ripple on the surface. The problem I'm having is halfway to the front of the tank I have a sort of film on the surface of the water. If I face the holes of the spray bar to the front of the tank it seems to give too much of a wrilpool effect in the tank (the tank is a 50cm cube). Is this film harmful? The fish all seem fine it just doesn't look nice. Any advise on how to break it up without putting too much current round the tank would be appricated

Is it an oily looking film? If so its probably just from the oils in your hands, drag a peice of newspaper across the surface, film gone.

It's like a whiteish film but I'll give that a go
