Aquarium Advice FINatic
Since I feed my discus beefheart and bloodworms, and I feed my other fish Tetra Min flakes.. The surface on my 92g constantly has an oily film on it.. I don't use an air stone, but my 2 spray bars are pointed up more to give surface agitation for o2. But I hate looking at the this oily surface.. Is there anyway to get rid of it besides water changes and a protein skimmer ? Would an airstone actually do it ?
