Nitrite vs Nitrate: The Aquarium Chemistry You Can’t Ignore
Nitrite and nitrate sound similar, but they affect your fish very differently. This guide explains what each one does, which is dangerous, safe levels to aim for, and how they fit into the nitrogen cycle.
Tank Cycling
Tank cycling is the essential process of preparing your aquarium so it can safely support fish. Before any livestock goes in, beneficial bacteria need time to grow and establish the nitrogen cycle. These bacteria convert harmful ammonia from fish waste into nitrite, and then into the far less toxic nitrate. A proper cycle usually takes several weeks and involves testing your water regularly to track ammonia, nitrite, and nitrate levels. Rushing this step can stress or even kill fish, so patience here pays off with a stable, healthy tank. Once ammonia and nitrite consistently read zero and nitrates are present, your aquarium is ready for its first residents.
