FAQ: Cycling fish tank?

Fish tank cycling is described in many different ways, such as; Breaking in; the Nitrogen cycle; nitrification; or quite simply ‘ cycling ’ – whatever name you choose to use, every new aquarium has to go through a process of forming friendly bacterial colonies.

How long does it take for a fish tank to cycle?

Just give the tank time. The cycling process usually takes six to eight weeks. 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 long does it take to cycle a tank with fish food?

The whole cycling process can take more than two months with fish food. There are some tips for tank cycling can be used to reduce significantly the time required.

Can you cycle a tank with fish?

When your water testing shows no ammonia and no nitrite despite regular feeding, cycling is complete, and you can start adding more fish to your aquarium. Adding too many fish at once can still create dangerous ammonia spikes as your biofilter struggles to catch up.

What does cycle fish tank mean?

What exactly is ‘cycling‘? It means you are creating a filtration system by ensuring there is a bacteria colony in it that removes toxic waste to ensure your aquatic life has a healthy environment to thrive in! There are two ways of cycling a fish tank – one with fish and one without fish.

How long will a tank stay cycled without fish?

It is possible for a cycle to complete in seven days with seeding; otherwise this method takes two to three weeks. The bacteria colonies produced using this method are large enough to handle a well-stocked aquarium.

What happens if you don’t cycle your tank?

Even if you didn’t cycle your tank before adding fish all hope is not lost. Ammonia is deadly to your fish in even small quantities. Luckily, there are bacteria that love ammonia and want only to consume it. This leads to another problem, though, the bacteria’s own waste product- nitrite.

Will Live plants help cycle my tank?

Can I put plants in a cycling tank? Yes, you can put plants in a cycling tank. Putting some live plants in a cycling tank is actually a good idea because it helps with the cycling process. Adding some live plants while cycling is especially a good thing if you’re doing “in-fishcycling.

How can I speed up my cycling fish tank?

1. Focus on the basics

  1. Keep the pH above 7. This one often catches beginners.
  2. Don’t turn off your filters. Most nitrifying bacteria lives inside your filter.
  3. Don’t forget the dechlorinator.
  4. Watch the heating.
  5. Use a cycled filter.
  6. Season your filter.
  7. Add gravel.
  8. Buy some plants.

Should you do water changes while tank is cycling?

While not essential, we recommend water changes during cycling, although opinions differ. Since bacteria live on surfaces, removing water does not disrupt their development. High ammonia can be beneficial for aquarium plants, but algae is also a plant, and indeed, unwanted algae blooms are common during cycling.

Will dead fish help cycle tank?

Rotting fish do create ammonia, so will cycle a tank.

What are the 5 steps to cycling a new aquarium?


  2. Stock your new aquarium with only a few hardy fish, and feed them sparingly.
  3. Test your water with an ammonia and nitrite test kit.
  4. If you already have an existing, healthy aquarium, you can introduce established filter media from that tank into the filter of your new tank.

How do I know when my tank has cycled?

Once your nitrite levels have reached a certain point a bacteria called Nitrobacter will develop. They’ll convert the nitrites into nitrates. When the levels of nitrite and ammonia reach 0ppm (parts per million), your tank has been cycled. Now, that’s not to say you can sit back a relax.

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

The easiest way to check your fish tank water is to buy a good all-round tester kit. The key things to look out for are ammonia, nitrite, nitrate and pH. These compounds will be kept largely in check with a good mechanical, chemical and biological filter.

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

The growth and establishment stages of bacterial colonies are what are referred to as “cycling” the aquarium. In all, it takes 4-6 weeks for the cycling to complete. The amount of bacteria that grow or colonize in the aquarium and filter is dependent on the amount of “food” (waste products) available in the aquarium.

Do you have to wait 24 hours to put fish in tank?

There are several benefits of healthy bacteria in a tank, these include recycling waste products and getting rid of any ammonia build-up. It is important that you let the tank sit for at least for 24 hours before adding the fish to ensure the build-up of healthy bacteria in the tank.
