Definition: Aquarium cycling, also known as the nitrogen cycle, is the process of establishing beneficial bacteria in a new aquarium to create a stable and healthy environment for fish. This process converts toxic ammonia from fish waste into less harmful nitrates through bacterial action.
Key Points:
- Stages: Involves the conversion of ammonia to nitrite, and then nitrite to nitrate by different types of bacteria.
- Duration: Typically takes 4-6 weeks, but can vary based on methods used and aquarium conditions.
- Methods: Can be done through fishless cycling or fish-in cycling, with fishless being preferred for fish welfare.
- Monitoring: Requires regular testing of ammonia, nitrite, and nitrate levels throughout the process.
