Stuff floating on top of tank

[Super4Ever]

I have a 120g tank being cycled right now at the house I'm moving into. Because I don't live there yet I don't get to check on it all the time. When I went there last I noticed some stuff floating on top of the tank. I was just wondering if anyone could tell me what it might be.

Does it look oily (it kind of does in the pic)? That happened to my with my 10g. I removed the oil film and changed my food and it went away.

I just removed it with a ladle and just skimmed it off without using the paper towel method.

Here's some info if it is oily. http://freshaquarium.about.com/od/problemsolving/a/oilslick.htm

it looks kind of like dust, which would be very prevalent in your house if you are just moving in. Does it have a lid? you might want to get one of those if not.

It may be dust. It has a lid, but it doesn't fit the best. I'll have to check again the next time I'm there.

OK, I have found that I also had oily residue on my sump tank. The main tank was recently containing oily residue and no matter how much surface agitation.... Still oily.. Today I decided to go a little further than just the weekly water change.. I changed the filter sock and instantly the oily surface was GONE.. I therefore can only recommend that you maintain a strict habit of cleaning your filters and whatever keeps your water clean and I am positive that your oily residue will be a thing of the past.. I have two tanks and I find that the tank I have at work, that does not get looked after as carefully as the one at home is the one that starts to have issues..
