‘The Nitrogen Cycle’ is the most important thing a fish keeper can learn about. It is an essential part of keeping fish alive and healthy in an aquarium.
What Is ‘The Nitrogen Cycle’?

‘The Nitrogen Cycle’ is a process in which bacteria convert toxic substances into less toxic substances. This is important in an aquarium as the toxic substances which fish produce naturally can quickly make them ill, or even kill them if not removed.
