what is the cause of a white film that is on the surface of my water? it builds up quite frequently. i stick a cup in the water and skim it off. i'm gonna try to get a pic when i can find my camera.
any ideas?

Do you think that an airstone on a timer would also accomplish this? I also have some of this film, but am not too annoyed with it. I'm also concerned with the off-gassing of the co2, although i'm using DIY and not pressurized.What you can try is hook up a PH to a timer. Aim PH at surface, and set time for night (when you need more O2 anyway).
This way during day CO2 stays in tank, at night surface is agitated and more O2 is avail for fish.
