Is 80 ppm nitrate bad?

At levels below 80 ppm, nitrates are not a problem. Levels above 80 ppm should not be ignored, as they can cause redness in the fins and cause fish to become very lethargic.

What is the ideal ppm your ammonia nitrite and nitrate should be?

Although many aquarists run their tanks with extreme nitrate levels, the ideal is a maximum of 5 to 10 ppm. Levels of 20 to 50 ppm are too high. Freshwater tanks can be at the higher end, with marine fish-only setups at the lower end and reef tanks as near zero as possible.

How long should nitrite spike when cycling tank?

After a water change, the nitrite spikes within 24 hours and then the nitrate will spike about 24-48 hours after that. However, the nitrite is still at extremely high levels even after the nitrate spikes.

Why are my nitrates so high?

Detritus, decaying plant material, dirty filters, over-feeding, and overstocking the aquarium all contribute to increased levels of nitrate. Additionally, tap water used to fill the aquarium may contain nitrate in it. In the United States, drinking water may have nitrates as high as 40 parts per million (ppm).

Is 5 ppm nitrate bad?

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.

How do you fix high nitrites in a fish tank?

First, perform water changes with dechlorinated water to reduce the nitrite level….Treatment of Nitrite Poisoning

1. Large water change.
2. Add aquarium salt (sodium chloride) or a marine salt mix.
3. Reduce feeding.
4. Increase aeration.

Which is more harmful to 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 is a good nitrite level for an aquarium?

Aquarium nitrite levels should be at an undetectable level at all times after the tank has fully cycled. While not as dangerous as ammonia, nitrite is still a highly toxic chemical, and causes stress for fish even at levels as low as 0.5 ppm. Levels exceeding ten to twenty ppm are lethal over a period of time.

Why are my nitrite levels so high?

Overfeeding and overstocking can lead to high nitrite levels, but incorrect filter maintenance and new tank syndrome are perhaps the most common cause. To speed-up the growth of bacteria in new filters you can transfer some media from an existing filter, or add a bacterial starter culture and food source.

How do I lower my nitrite in fishless cycling?

Add small quantities of certified aquarium salt (¼ oz per gallon at most) to freshwater tanks to keep toxin levels healthy and reduce nitrite toxicity during and after the cycling process. This helps pose less stress on your growing bacteria, live plants, and fish (if you choose to not follow the fishless method).
