Nitrate levels should be less than about 20 ppm in order to ensure healthy fish. If a reading shows that your tank has high nitrate levels, there are several steps you can take to lower them.
What is an acceptable nitrate level?
Safe Level
Drinking water with concentrations of nitrate (measured as nitrate-nitrogen) below 10 milligrams of nitrate per liter of water (mg/L) is considered safe for everyone in your family. 10 mg/L is the U.S. Environmental Protection Agency standard for nitrate in drinking water for public water supplies.
At what level is nitrate harmful?
Natural processes can cause low levels of nitrate in drinking water—usually less than 3 mg/L. The health concern is with levels of nitrate over 10 mg/L.
How do I lower the nitrate in my fish tank?
Water changes: Performing regular water changes with water that has little or no nitrate will lower the overall nitrate level in the aquarium. If your local tap or well water is high in nitrate, using deionized water (DI) or reverse osmosis water (RO) can help keep nitrate levels low when doing a water change.
What is a good nitrate level for freshwater fish? – Related Questions
Will changing filter lower nitrates?
There are various devices and procedures that can lower nitrates in an aquarium. Nitrate-adsorbing filter media and anaerobic denitrifying biofilters will remove dissolved nitrate, but they will do nothing to eliminate the cause of the problem. The simplest solution is a water change.
Does water conditioner remove nitrates?
Nitrate can be removed from drinking water by distillation, reverse osmosis or ion exchange. A water softener is typically used to treat hard water, but it can also remove nitrate and nitrite with the proper media. Water softeners use an ion exchange process, during which minerals are replaced with sodium.
How do you get rid of nitrates fast?
The quickest and easiest way to get nitrates down in your setup is to change the water. As long as your tap water has a lower nitrate level than your tank water, by replacing it, your nitrate level will go down. Test the nitrate level in both your freshwater tank and your tap, to ensure that this is the case.

What can I add to my fish tank to lower 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.
What causes high nitrate in a fish tank?
High nitrate is often seen in aquariums with high bioload — meaning that lots of fish poop, dead leaves, leftover food, and other rotting organics are in the water. Hence, the easiest methods to reduce nitrate in the long term include decreasing the number of fish and/or amount of food that goes into the tank.

How do I lower nitrates without a skimmer?
I would also take the time to clean the tank- use a turkey baster to clean the rocks/sand or vacuum the sand bed to remove as much stagnant detritus as you can. After that, continue with water changes or possibly incorporate macro algae for nutrient export.
What to do if tap water is high in nitrates?
Nitrate. Removing it from drinking water: Treat water using ion exchange, distillation, or reverse osmosis. Find treatment systems certified to remove nitrate.
How do you get rid of nitrates naturally?
What can we do to aid in the removal of nitrates from the aquarium?
- Add live plants to a freshwater aquarium. Plants naturally utilize nitrate as a nutrient and food.
- Reduce fish population or upgrade to bigger tank.
- Cut back on feeding.
- Use a nitrate remover such as ALGONE.
How much nitrate is too much for 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. Click here for more information on Nitrate.

How do I know if my fish has nitrate poisoning?
In goldfish, nitrate poisoning occurs when the fish is exposed to a high level of nitrate over a period of time. Some symptoms of this chronic condition include lethargy, breathing problems, abnormal swimming or movements, fading color, and curled body.
Can a fish recover from nitrate?
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.
