oil slick

Why do i have what looks like a oil slick on the surface of my water.

You need more surface agitation. Add a powerhead or reposition your filter output. And it should go away.

i had that one time and couldnt figure it out! come to find out, i never plugged my filter back in! haha

It can also be caused by having something like hand cream on your hands and putting them into the tank.

From what I figured out it is a build up of organic proteins, more surface agitation from your filter or a bubbler should clear it up with in an hour.
