The single most important water chemistry concept is the Nitrogen Cycle . In a newly set-up aquarium, ammonia levels will initially rise as waste breaks down. This ammonia is highly toxic to fish. Over time, beneficial bacteria grow that first convert ammonia to nitrite (which is also toxic), and then another type of bacteria converts nitrite into nitrate (which is far less toxic). The process of building up these bacteria populations is called "cycling the tank." This process takes several weeks and must be completed before adding any fish. Until you see your test kit read zero for ammonia and zero for nitrites, your tank is not safe for fish.

By following these steps, you can ensure a seamless, peaceful experience with your virtual aquatic environment.
