Hope this is the right place to post this. Last night I checked my tank and when I lifted the lid, there was a thin kind of film on top of the water. Not an algae film, just a very light slighly white film. I never noticed this before. I recently added a amazon sword plant. Has anyone seen something similar? I did a 20% water change two days ago and the film was not present. Last night I changed about 10% hoping to get rid of it. The water change got rid of most of it but I would like to know what caused it and if anyone thinks it could be a problem.

Your filtration sounds inadequite if you're experiencing a build up of film on the surface and it sounds like you're especially not getting enough surface agitation. Try powerheads, a higher gph filtration system or add another, the build up simply sounds like waste material.

Thanks for the advice. I think that the lack of surface activity may be the cause. I get some surface action from my filter. However the sword plant reachs the top of the water so the plant may very well be preventing the flow more than is good. Guess its time for a powerhead. To answer thePACK's question I mainly feed shripm and beefheart, with the occasional feeder and krill. I have been leaving the uneaten parts in the tank as he always comes back and finishes it up. I'll try taking out the uneaten pieces and see if that helps.
