What Is the Nitrogen Cycle in a Marine Aquarium?
The nitrogen cycle is the process of converting toxic ammonia into less harmful nitrite and then nitrate through beneficial bacteria.
How to Cycle Your Marine Aquarium?
- Fishless Cycling: Add an ammonia source and monitor water parameters until the cycle is complete.
- Live Rock Cycling: Use live rock to introduce beneficial bacteria and speed up the cycling process.
- Use Established Media: Seed your tank with filter media or substrate from an established marine aquarium to accelerate the cycling process.
How Long Does Cycling Take in a Marine Aquarium?
Cycling typically takes 4-6 weeks, but it can vary depending on the method and conditions.
