Tony s Posted January 28 Share Posted January 28 Protein film. Possibly from over feeding. No worries. I get this also. Use a paper towel laying on surface flat. Comes right off. You can also get a skimmer to keep it out. Not harmful but it can reduce oxygen exchange at the surface Link to comment Share on other sites More sharing options...

Air stone, sponge filter etc. ya know, I would have never thought of that. But just something to break the surface tension.
