I'm not familiar with the type of filter you are using but if you can create some agitation on the surface of the water, that should take care of it.

The surface film is a protein scum. It is caused by organics, and can occur from time to time. I see it minimally in a couple of my tanks, never in others. Regular partial water changes of 50% weekly, good filtration, not overfeeding, and not overloading the fish load all work to keep it minimal or non-existent. When you do the water change, invert the siphon and remove it; this will at least keep it less. Water movement at the surface also helps to keep it from forming, the filter flow directed across the surface, or with a surface skimmer attachment to the filter, depending upon the type, will all help too.

As for the cloudiness, that is likely a bacterial bloom. Same "treatments" as those mentioned above. Plus good vacuuming of the substrate during water changes (not around plants though).

Correct, no medications or chemicals will help this, only make it even worse.
