Oily film on a rather new tank

So this morning there was a new surprise waiting for me...an oily film trapping a bunch of CO2 bubbles. Is this a new tank issue (been running two weeks), or possibly too much decaying plant matter as I did not completely cut back a Blehari sword. I was worried to much pruning would be worse than leaving a few "sick" leaves.

If it just happened once, then see if you can blot it up with a paper towel.

If it keeps happening then look for the source. A scum that thick suggests something is going on. That is too much film.

If it is just a little bit of film (this is normal) then increasing the surface action can keep it moving so the filter can trap it.

Also, check ammonia levels.

Ammonia is 0, but I still have a small amount of Nitrite between 1.0 and 2.0 ppm. Should I cut back the remaining melting leaves on the sword?

You maight have solved your problem, but search the internet for biofilm in aquarium context. Knowing what you deal with is alsways useful.

Ok, so I cleaned out some of the film, upped the speed on my filter, trimmed out some of the dying leaves on my Sword, and did a 25% water change. Hopefully that takes care of the issue.

I had this and someone recommend more surface movement. So repositioned my return and it went away.

How much driftwood do you have and are they new pieces?

There is no driftwood in the tank.

But it appears that the increased circulation kept the film from forming over the entire tank. There is still a little bit left, but not enough for me to worry about.

if you cant figure out and the film keeps coming back, an eheim surface skimmer will get the job done.
