Definition: The Nitrogen Cycle, also known as the biological cycle or nitrification process, is the natural biological process in an aquarium where beneficial bacteria convert toxic nitrogen compounds into less harmful substances. This cycle is crucial for maintaining a healthy aquatic environment.
Key Points:
- Stages: Involves the conversion of ammonia to nitrite, and then nitrite to nitrate by different types of bacteria.
- Importance: Essential for breaking down fish waste and uneaten food, preventing toxic buildup in the aquarium.
- Bacteria Involved: Primarily Nitrosomonas (converts ammonia to nitrite) and Nitrobacter (converts nitrite to nitrate).
- Maintenance: Requires regular water changes to remove accumulated nitrates and maintain balance.
