Your new freshwater fish and critters will consume food, which they will then excrete as waste products in the tank.
The uneaten food leftovers, decaying algae, and the dead plant leaves also slowly decompose in your tank, adding to the waste quantity.
Additionally, more bioload means more waste output per fish as some species are messier than others. Eventually, the organic waste degrades into Ammonia NH 3 , which is lethal to aquatic fish and invertebrates.
Different sets of beneficial bacteria that live in the water will transform the Ammonia into Nitrates which are relatively harmless when kept low through water changes. Before a fish tank becomes inhabitable it needs to go through the Nitrogen cycle so that the beneficial bacteria could process the toxic Ammonia from fish waste. However, biotechnology has made it possible for you to shorten it to about two weeks, through the help of some beneficial bacteria products.
You also should bear in mind that small tanks are very sensitive to seemingly insignificant changes in their water chemistry.
