The air stone m00se is talking about will work very well, i know many members here who do that.
or as i said a surface skimmer.
another thing that helps is when you do your WC only skim the surface.
i think i said this earlier but i have a tank that i feed maybe twice a week, and it has bio-film. i do not beileve that bio-film is a protien issue, i think it is just waste from bacteria in the tank.
