Slime on the surface

I have this thin layer of something on the surface of my 10 gallon nano. It looks like oil, with out the rainbow coloring, and I think it's due to lack of surface agitation, so could someone tell me a good way to solve this?

The best medicine in your medicine cabinet is clean water.

I point my jets ( filter outlet) to the surface from below, without splashing. That does it for me.

I used to have a cheap plastic "surface skimmer" connected to the canister filter intake. That is the official way to do it.

A heavily planted shrimp tank is possible!

Air stone at night. You know the fix! No surface agitation so agitate the surface!

Those Hagen "surface skimmers" work well. The only drawback is that they're pretty big.

Its biofilm.
You can help get rid of it by doing water changes and increasing surface movement. Eventually it will go away on its own.

For now, simply take a cup and remove as much of the bacteria and gunk as possible.
Throw it out. Do a water change.

Increase surface movement as others said through filtration or by bubbles. :^)

It can be caused by fat and oils from leftover food. You can take a paper towel and drag it across the surface a couple times to get most of it.

I don't have any fish in it yet so the oils/fat is crossed out, but i will keep that in mind when I do get fish. I aimed the filter output at the surface and for a while it dissapeared, but then I woke up this morning and it was completely covering the surface.
