Hello, my name is Maurice and this is my first post since becoming a member. I'm having an issue with organic film on the water surface. This is not due to overfeeding since the aquarium has a light load of fish (22 Neon Tetras, 16 Rummy Nose Tetras, 13 True SAEs, 2 Bristlenose Pleco in a 90 gal aquarium). I know of only two ways to get rid of this film; either thru surface skimmers or certain types of fish (Swords, Mollies etc.). Is there another way to get rid of this film because I do not want to add anymore fish nor do I want to set up a skimmer? I would ideally like to keep the light load of fish and not add anymore equipment to the aquarium. Are there any other alternatives to remove the organic film? I am currently skimming the surface during water changes and this works well, but I am looking for a more practical solution. Any ideas? Thank you.
