weird Film on Water

did you recently change your filter catridge? Most cartridges come with carbon which will release carbon dust into your tank which would make your tank cloudy. Is they film black as you said it was like oil. If so, the chances are its carbon dust. It is not "deadly" to your fish it just makes the water a little cloudy for an hour or two.
OMG I just saw something like this too, and I freaked, thinking it must be soap or something... I figured I or my honey forgot to rinse our hands really well before doing a water test or something, and I heard that soap is really really bad for fish.... and if it's not soap, it's gotta be something else bad, so I decided to see what I could do to get rid of it.
So I took my gravel vac, and skimmed off as much as I could, and it looks much better now (24 hours later, doesn't look filmy/soapy anymore). The trick was to let the plastic part of the gravel vac (or you can probably use any aquarium-friendly soap-free container) to just barely tip under the surface of the water, so the very top layer of water almost looks like it's getting sucked in. You will be able to watch the filmy layer as it goes in, just keep going until you can't see it anymore.
Now, that said, I am wondering whether "what I can't see, can hurt". Anyone else have more to add?
