| Ammonium is considered to be the first decomposition stage in the nitrogen cycle. It consists of proteins, which are converted by heterotrophic bacteria to ammonium. In addition, fish excrete a percentage of their bodily weight into the water every day in the form of ammonium. Ammonium is non-toxic, but, with increasing pH-levels, is converted to an ever-greater degree into toxic ammonia. Only for freshwater aquariums. Indispensable for heavily-stocked, unplanted aquariums and for the transport of fish. 1 kg absorbs 5000 mg of ammonium, reducing the nitrites and nitrates produced as a result. |
