This process normally takes anywhere from 2-6 weeks. At temperatures below 70F, it takes even longer to cycle a tank.
Why is my fish tank high in nitrites?
Overfeeding is the number-one cause of high nitrate levels in aquariums. Overfed fish produce much more waste than normal, and when more food is given than they can take in, the uneaten food rots and produces even more wastes.
Can fish recover from high nitrite?
Though fish can recover from poisonous nitrate levels they will likely become very sensitive to nitrates in the future. In the most severe cases, a fish that’s poisoned can die in less than 24 hours. For this reason, you should react quickly and start immediate treatment as soon as you notice the problem.
How long does it take for nitrite to go down?
Any measurable ammonia levels should be gone within 24 hours and any measurable nitrites will be eliminated within 48 to 72 hours of dosing. So if you had ammonia it will be gone.
How long does it take to lower nitrites in aquarium? – Related Questions
What is the fastest way to reduce nitrites?
What should I do?
- Complete a 25% water change and retest after a few hours.
- Add Fast Filter Start to boost the natural bacteria in your filter to process the extra nitrite.
- Support the health of your fish using Aquilibrium First Aid Salt.
- Continue to regularly test your water.
How do you lower nitrites quickly?
How do you reduce nitrite levels?
- Water change! A 30-50% water change should be the first thing you do after confirming a nitrite spike.
- Add cycled filters. As I touched on earlier, bacteria turn nitrites into much less harmful nitrates.
- Water conditioner. This is essentially a nitrite remover in a bottle.
Why can’t I get my nitrite levels down?
Doing water changes is the only way to get your nitrites down. Keep up the changes and remember that water changes do not slow down a tank cycle. You have to grow the nitrite eating bacteria and that bacteria will reduce them to 0. If you keep removing every bit of them with water changes, you can’t grow the bacteria.
What levels of nitrite are acceptable?
EPA has set an enforceable standard called a maximum contaminant level (MCL) in water for nitrates at 10 parts per million (ppm) (10 mg/L) and for nitrites at 1 ppm (1 mg/L) [EPA 2002; EPA 2012]. EPA believes that exposure below this level is not expected to cause significant health problems.
What level of nitrite is toxic to fish?
Nitrite levels above 0.75 ppm in water can cause stress in fish and greater than 5 ppm can be toxic. Nitrate levels from 0 – 40 ppm are generally safe for fish. Anything greater than 80 can be toxic.
Will nitrate go down on its own?
The nitrates should break down some at the end of the cycle but they will always be there in some quantity. Personally I strongly recommend getting rid of the API kit and going with Red Sea, Salifert, etc.
What is the fastest way to lower nitrates in an aquarium?
Removal is simple enough if you carry out large, regular water exchange. Water changes are a sure shot, as they instantly and permanently remove the nitrate from the system. Want to remove 20 percent of the nitrate in the water? Do a 20 percent water change; it’s as straightforward as that.

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 long do nitrite spike last?
It can take 4-6 weeks for your aquarium to cycle. So you just need to wait. You don’t need to do any water changes, this is only required when doing a cycle with fish so the ammonia/nitrite is kept low.
What causes nitrite to increase?
Overfeeding and overstocking can lead to high nitrite levels, but incorrect filter maintenance and new tank syndrome are perhaps the most common cause. New filters (and media which has been washed in tapwater or replaced with new) contain few bacteria and aren’t capable of removing much pollution.
What is worse for fish ammonia or nitrite?
Ammonia is harmful to fish (and should be ideally kept at the 0 ppm and becomes very dangerous at 1.0 ppm or greater). Nitrite is even more harmful and should also be kept at 0 ppm, as it suppresses a fish’s ability to carry oxygen in its bloodstream. Even slight amounts can stress fish.
What kills fish nitrite or nitrate?
Nitrite and nitrate sound very similar and are often confused, but nitrite is very toxic to fish even in low levels, whereas nitrate is less toxic and builds up. A nitrite level of just 1 part per million is enough to poison and kill most aquarium fish, yet nitrate levels can be 100 times that in some cases.
How long can fish live with high nitrates?
Eventually, fish death will begin, occurring over a period of a few days to a few weeks. When fish are suddenly exposed to very high nitrate levels, they will usually die within 24 hours of exposure. Often owners are not aware of the problem until the fish are dead or near death.
