    I have a ton of biofilm on the surface of the water in my tank. How do I get rid of it?[​IMG]

    Following. I'd love to hear how, too. My bladder snails put on quite a show eating it, though.

    I'm not seeing any surface movement? The water breaking the surface from your filter output should break up that film. You can also lay a paper towel on the surface and it should absorb the film.

    Do you have an airstone? You need more surface agitation to get it circulating. I would also do a water change and vacuum really well. The biofilm is usually from decaying food/waste on the bottom. We all get it, it's just that with proper surface agitation it won't build up like that.

    You can get a cup and slowly scoop it off the surface before you vacuum if you want. A paper towel works too. I was told to lay newspaper on top and peel back gently to remove mine, but I never tried it. The airstone was what ultimately worked. (Back with my first tank)
