What kind of skimmer? Is it in the sump or a Hang On type? The skimmer may be working just fine, but you may need a surface skimmer box of some sort.

this is happening a lot lately in my tank. in my case (probably yours as well) is because the water going into the skimmer is not being removed from the surface. if your skimmer is the hang-on type, you need to adjust or modify it to make sure the water is removed from the surface.
if you have an overflow box (my case), you have too much turnover flow and the water falling into the overflow is coming from slightly under the surface, allowing nutrients buildup above this line.

There ya go...
The remora uses a powerhead that sits far too low in the water column. You can shorten the clear hose that connects it to the skimmer and use a second powerhead to push water 'chop' into the intake power head, but that will not do the job 100%.
You really need to get that pre-skimmer box that fits the powerhead. The problem with them is that they are big, and ugly. You could make a smaller one with acrylic and weld-on. Other than that, you need to find SOME way for the intake to the skimmer to be taking water from the surface.
I have the same skimmer on my 26 bow. I'm drilling the back for an overflow. I've made a small sump to be placed under the stand. I'm putting my remora in there. Not only will the new bulkhead/overflow skim the surface of the display, but having the skimmer in the sump will reduce the bubbles I get when I feed.

The oil is a byproduct of the foods that you feed. It can also be some of the waste from your tank's inhabitants. Finally, it could also be YOUR oils that come off very quickly in salt water when you put your hands in.
In any case, it screws up the gas exchange in your system. Until you can effectively skim the top, use a powerhead, facing upward to break it up.

Yep... that should be fine for now. As long as it is not a 'slick'. The chop in the water surface should help with gas exchange, as will the skimmer itself.
Again, the best thing to do is solve the surface skimming problem. With other skimmers I made a surface skimmer with 3" PVC and an endcap.
