Initially (1) there is no ammonia in a new system. With time going by, addition of exogenous ammonia, a bit of food, some live rock... ammonia accumulates and populations of chemo-autotrophic bacteria that can utilize it as well. As these first ammonia-utilizing micro-organisms increase in number, their by-product of nitrite (2) begins to accumulate triggering the beginning of a second group of species of nitrifying bacteria (3) that begin to populate the aquarium, converting the nitrite in

Nitrification occurs principally through bacteria (e.g. Nitrosomonas) metabolizing ammonia to nitrites (NO2-) and other groups (e.g. Nitrobacter) in turn converting nitrites to nitrates (NO3-). Lets look at this in another way (refer to Figure 3); an "idealized" time line for establishing nitrogen cycling in a new marine aquarium:

At mark "0" youve just set up your system and placed all new (read that as sterile) marine water (synthetic). In most cases, the hobbyist will shortly thereafter ("1") introduce either A) Some hardy (nitrogenous waste resistant) fishes, such as damsels to help "pop" t
