Oxygen gets into water by diffusion from the surrounding air, by aeration (rapid movement), and as a waste product of photosynthesis. When performing the fade out oxygen test, only grab samples should be used, and the analysis should be performed immediately. Therefore, this is a field test that should be performed on site. Total fade out gas concentrations in water should not go along 110 percent. Concentrations above this level can be harmful to aquatic life. F ish in waters containing excessive turn gas! es may suffer from gas bubble disease; however, this is a very rare occurrence.
