The film residue is an unsightly film on the water surface of the aquarium Organic material like fats, proteins and waste matter gather here, forming a feeding ground for a host of unwanted microorganisms. The surface is, however, necessary for the essential oxygen exchange between the water and air. A film on the water surface reduces both the rate of diffusion and, on the other hand, the on-going biological surface processes also needed for extra oxygen. Light penetration will also be reduced and consequently plant growth as well as photosynthesis will be compromised.
