I've had a 20 gal. freshwater aquarium for about 6 months now. Recently almost all of the fish died and I'm not sure what's wrong with the tank. I tested the water and it seems to fine in terms of Gh, Kh, PH, nitrites and nitrates. The filter is working properly (I think, although I'm not sure how often I should be replacing the sponge pad or the carbon filter). I've noticed that there is a film, kind of like oil without the rainbow, on the top of the water. Anyone know what this might be? I change the water (about 20%) every couple of weeks. There also seems to be quite a buildup of algae on the fake rock things that I put in there. Is that bad? I bought an algae eater fish but it died before a week or so. If I need to get rid of the algae, what is the best way to do it? Just scrub it off with a brush? It seems like it would stay floating in the water unless I changed almost all of the water out, and I don't think that is good for an established tank either, please help, frustrated!
