in my frag tank which is a rimless open top tank- I have a film on top of the water. It’s not slimy, and also has no “rainbow” effects like it’s oily. Seems more like very fine dust. The air conditioner intake is near by, but it’s sucking air, not blowing air. I have three other tanks in same room also with open tops and none of the others have this issue. Other then this film or dust on the surface the tank is otherwise going well.
the power head hits surface and I have a over the back over flow that should be skimming the water surface, but no matter what I can’t seem to get this film to go away.
Any suggestions on how to deal with this film?
