Problems with excess levels of nitrogen in the environment Lake and reservoir eutrophication can occur, which produces unsightly scums of algae on the water surface, can occasionally result in fish kills, and can even “kill” a lake by depriving it of oxygen
Is 1 ppm of ammonia high?
Any levels of ammonia and/or nitrite above 00ppm should be considered dangerous and, if present, it must be assumed that there is not enough bacteria compared with the fish Levels above 10ppm of ammonia or nitrite could kill fish, or make hardy fish ill
