Where Do Nitrates Come From?

Before we get started, it is important to understand where nitrates come from, so that you can avoid a build-up of high nitrate in freshwater aquariums. The main cause of nitrates in your freshwater aquarium is the nitrogen cycle. You have no control over this, so there will always be nitrates. But you can use nitrate removers.

The nitrogen cycle begins with waste creation. This can result from fish poop, uneaten food, or the presence of dead plants and leaves. Various bacteria convert the wastes into ammonia, which is toxic. The second stage of the cycle converts the ammonia to nitrate. In the final stage, the nitrites are converted into nitrates by other kinds of bacteria. And this cycle continues.
