How do I speed up the nitrogen cycle in my fish tank?

Adding filter media, rocks, or substrate from an existing tank is the single most effective thing you can do to speed up the nitrogen cycle in your aquarium.

How long should a new tank run before adding fish?

Wait until both the ammonia and nitrite levels have risen and then fallen to zero before adding more fish. It usually take about 3-6 weeks for a new aquarium to go through the initial nitrogen cycle, so fish should be added only a few per week during this time.

How do you know when your tank is cycled?

After testing your aquarium water for ammonia and nitrite and nitrate, if the reading shows 0 ammonia, 0 nitrite, and some nitrates then your fish tank is cycled. Cycling a new tank usually takes between four to six weeks.

How do I put good bacteria in my fish tank?

Add Filter Media One of the most effective ways to make sure beneficial bacteria exist in your fish tank is by adding filter media. This will speed up the nitrogen cycle, which will also help remove ammonia from the fish tank since beneficial bacteria feed on ammonia and turn it into harmless compounds in your tank.

How long does it take for good bacteria to grow in a fish tank?

4-6 weeks
Normally, it takes 4-6 weeks for the growth of beneficial bacteria to complete the nitrogen cycle in a new aquarium. It is not unusual for seeded aquariums to fully cycle in half the time it would normally take, thus allowing you to stock more fish in the new tank sooner.

How do I know when my fish tank is ready for fish?

When Is My Tank Ready for Fish? Your tank is ready to add fish when your ammonia tests are quickly dropping over the course of a day, and your nitrite level has risen and subsequently dropped back to 0ppm. Once you reach this point, you are ready to add your first fish.

How often should you add beneficial bacteria to your aquarium?

You need to add bacteria to an aquarium as often as you add new fish to the tank or change its water. If you change your aquarium’s water once every two weeks, then you need to add bacteria to your tank two times a month. This ensures the bacteria can keep up with the waste conversion.
