This is the process in which the nitrogen cycle works. Ammonia is created by urea and decomposition. Ammonia is turned into nitrites by nitrosomonas bacteria. Nitrites are less harmful than bacteria, but still pose a threat. Nitrites are converted to nitrates by nitrobacter. Nitrates are much less toxic and is used as fertilizer for live plants. It is harmful in great quantities, however, and should be avoided in the reef tank. ...
