Hey guys. I have a 90 gallon aquarium set-up in my bedroom. The tank has an AC - 110 and some random whisper filter on it, 2 AC powerheads (AC 50's i believe), a 6in airstone with pretty good air pump, and a bare bottom. The Tank currently has five 4-5in Peacock Bass (monos), and a 6 or so inch silver arro. The issue I'm running into is that i seem to have a film on the surface of the water, and the film is basically only visible if you look at the surface of the water from below the surface. Ive read that its just decaying organic matter, and that its not particularly harmful in a freshwater set up, but with the tank being in my bedroom, Its incredibly annoying and it bothers me a lot. I was thinking protein skimmer, as was my friend who's experienced with saltwater tanks, but I've read that it just doesn't work in fresh (something to do with the surface tension of the water maybe?). Do you guys have any suggestions for me to get rid of this? Thanks in advance for any info.
