Have you ever noticed oil slick in your Aquarium, where does the oil slick-like film come from in your aquarium?

This.Bio-film - is a thin film on the surface of aquarium water, caused by the build up of protein from organic waste material. It is the structure bacteria build to support themselves growing on the surface where they get access to oxygen.
Ya... agreed. I notice this is all of my new tanks. The film usually goes away a month after the tank cycles though. I usually just use a single paper towel draped across the water to get it off.

i have the same skimmer from eheim for about 6 months now with no problems, some thing you can do if you have breeding fish or small shrimp is take some screen mesh and cut it out to fit the intake, i had to do this to mine due to clippings getting stuck in there and running the pump low on waterI noticed this on my new tank. I assumed it was from my sand substrate (Black Diamond blasting sand from Tractor Supply). I noticed it has small metallic specs in it along with the oily looking film. I rinsed the sand many times in a bucket, and it appeared to be the same film. I also noticed the film showed back up when I stirred up the substrate to put in driftwood and plants. I ended up just getting an "Eheim Skim 350" surface skimmer pump. I left it on high for about 20 minutes and the entire surface was clear. Since the high setting also pulled in some bubbles, I reduced it to low (by using a simple shutter style slide switch), and now I have a crystal clear surface with no added micro bubbles in the tank. Best $26.24 I have spent so far!
I know what you are saying about the plant clippings finding their way in there. Do you have a pic of yours? The screen doesn't interfere with the skimmer being able to pull the skim off the surface?i have the same skimmer from eheim for about 6 months now with no problems, some thing you can do if you have breeding fish or small shrimp is take some screen mesh and cut it out to fit the intake, i had to do this to mine due to clippings getting stuck in there and running the pump low on water
