After about eight weeks, your ammonia and Nitrite levels should be acceptable (about trace levels), and you can add more fish. Do not add more fish until the ammonia and Nitrite levels have both dropped.
How do you start a 10 gallon fish tank?
How do I cycle my fish tank for the first time?
- When setting up your aquarium, only add a few fish at the start.
- Feed your fish very lightly at first and then gradually increase the amount over the next four to six weeks.
- You can significantly speed up the aquarium cycling process by adding beneficial bacteria from the onset.
How do I know my tank is cycled?
Once the nitrate-forming bacteria take hold, nitrite levels fall, nitrate levels rise, and the tank is fully cycled. Your tank is fully cycled once nitrates are being produced (and ammonia and nitrite levels are zero).
