Hi Ya'll, I'm sure this problem has an elegant solution but I cannot find one mentioned anywhere online or in books. I have a thin skin on the top of my aquarium water. It looks like oil but when I stir it, it clumps which is weird. Have I been putting my arm in there too much and gotten oil in my tank which is settling on top? Is it a common build-up of some sort? I do a 50% water change every week. What could be building up? I have already tried laying thin newspaper on it and picking up the newspaper but it didn't seem to soak any of it up. Please let me know what may be the cause and how to remove it. I suspect it is something really common that I have never come across.
