How long does it take for nitrifying bacteria to grow?

This process normally takes anywhere from 2-6 weeks. At temperatures below 70F, it takes even longer to cycle a tank. In comparison to other types of bacteria, Nitrifying bacteria grow slowly. Under optimal conditions, it takes fully 15 hours for a colony to double in size!

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

Normally, it takes 4 to 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.

What do nitrifying bacteria need to grow?

Nitrifying bacteria are traditionally considered to be obligate aerobes; they require molecular oxygen for reactions in the N oxidation pathways and for respiration. They are reputed to be microaerophiles, however, who thrive best under relatively low oxygen conditions.

Can you add too much nitrifying bacteria?

Yes, you can't overdose on it. I generally use x3 times the minimum dosage. It's better to be over versus being under on bacteria.

How long does it take for nitrites to turn into nitrates?

After a water change, the nitrite spikes within 24 hours and then the nitrate will spike about 24-48 hours after that.

All About Nitrifying Bacteria in Your Aquarium: What they Are and Where Can You Find Them

Do nitrifying bacteria need sunlight?

You don't need a light for the cycle, but I find it helps the tank as a whole because it gets the tank used to the lights and your basic algae can begin to develop. But no, you don't need light to cycle.

Why do I have no ammonia but high nitrite?

Many times the bacteria can quickly handle the overdosing of ammonia and you will get a zero (0) ammonia reading but the nitrite just gets higher and higher. High nitrite is very common when you rush the process or add too much ammonia too quickly. High nitrite inhibits the bacteria and stalls the cycle.

How do I know my 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. Cycling your fish tank can take a long time.

How long do nitrifying bacteria live?

Nitrifying bacteria being fed a given amount of ammonia can survive for a month or more without that ammonia source and when reintroduced to the same amount they almost immediately are able to process the same amount.

How long does it take nitrifying bacteria to double?

At temperatures below 70F, it takes even longer to cycle a tank. In comparison to other types of bacteria, Nitrifying bacteria grow slowly. Under optimal conditions, it takes fully 15 hours for a colony to double in size!

How long does it take for beneficial bacteria to consume ammonia?

Ammonia, nitrate and Nitrite tests will best determine how long. If it takes 2-3 weeks- Great. If it takes 2-3 months, so be it.

How fast does beneficial bacteria eat ammonia?

The cycling process usually takes anywhere from 4 to 8 weeks. During this period beneficial bacteria multiply to the point that they can absorb the harmful ammonia and nitrites as quickly as they produced.

How can I speed up the bacterial growth in my aquarium?

Can you add too much beneficial bacteria to a tank?

You can't add too much good bacteria to a fish tank. The beneficial bacteria will feed on the amount of ammonia available for it. If there are more bacteria than food, the extra bacteria will die or become dormant. A more common problem is not having enough nitrifying bacteria.

How often should I add beneficial bacteria to my tank?

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.

Can a tank cycle in a week?

With the use of starter bacteria products, cycling time can be shortened to a week plus. After filling the tank, we recommend letting the tank soak for a couple of days without running the filter. On the second or third day, do a 100% water change then start running the filter.

Does green algae mean my tank is cycled?

At some point in the process, you'll notice the beginnings of life in your sterile tank, in the form of an algae bloom. This is a sign that the cycle is nearing completion – there are enough nitrates in the tank to support algae. Get your water tested; either do it yourself, or have your LFS test it.

Does Brown algae mean my tank is cycled?

Brown algae is very common in new tanks. Normally, a few weeks after a tank starts to cycle, diatoms start to appear in the tank. Before the nitrogen cycle gets up and running, the nutrient balance in the tank can be out of whack. The diatoms pop up to eat these excess nutrients.

How high will ammonia get during cycling?

We sell Ammonium Chloride at the front of the store. The ammonia level in your tank will spike, reaching levels above 1ppm, then it will turn into nitrite and finally nitrate. Again, this process usually takes several weeks. It is important to wait until your ammonia levels reduce to 0ppm before adding fish.

How long do nitrite spikes last?

Nitrites can appear "stuck" for a period of time before dropping. When they start to go, they can go over night, however. I would guess about a week to 10 days before they go. Make sure you do no cleaning of that tank or clean the gravel.

What speeds up the ammonia cycle?

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.

What do you feed nitrifying bacteria?

All species of nitrifying bacteria require a number of micronutrients. Most important is the need for phosphorus for ATP (Adenosine Tri-Phosphate) production. The conversion of ATP provides energy for cellular functions. Phosphorus is normally available to cells in the form of phosphates (PO4).

What temperature should nitrifying bacteria be?

The optimum temperature for the growth of nitrifying bacteria, according to the literature, is between 28° C and 36° C, although an optimum temperature of up to 42° C has been reported for Nitrobacter by Painter (1970).

How long does nitrogen cycle take?

Even with the addition of bacteria supplements, the nitrogen cycle can take between six and seven weeks to complete and stabilize.
