BIOLOGICAL ACTIVATOR THE NITROGEN CYCLEAquariums are enclosed environments, in which as opposed to natural environments such as the sea, lakes or rivers, there is no guarantee of continuous change of water. Inside the tank, as in nature, pollutants and toxins are produced by the metabolism of the organisms living there. These substances must be adequately equalized to avoid harming the health of fish, plants and invertebrates. The decomposition of organic nitrogen such as, the amino acids present in waste products, in the putrefacation in organic substances and left over food, constitute a constant source of ammonia through a process known as “Ammonification”. This process is set in motion by specific bacteria which, by breaking down the amino nitrogen, frees ammonia. The ammonia m ...
