There are many benefits to have live plants in an aquarium. Apart from your aesthetic pleasure, live plants promote a healthy environment in an aquarium.
Aquarium wastes produce ammonia and nitrate, and those are toxic gases, while live plants can utilize ammonia and nitrate to reduce harmful gas concentration.
Live plants also absorb carbon dioxide and add oxygen by the photosynthesis process. Many aquarists grasping the usefulness of live plants in an aquarium, search for suitable ones.
In this article, we’ll talk about the best aquarium plants to reduce nitrates. We hope your exploring is going to be more manageable with this.
There are many types of aquatic plants to use in aquariums. All plants with green leaves can utilize bad gas like ammonia, nitrate, and carbon dioxide to add oxygen through the photosynthesis process. Here we listed some popular kinds of plants that you can consider the best aquarium plants to reduce nitrates.
Moss balls are round in shape and look impressive. They are very straightforward to maintain and perfect for beginners.
Moss balls grow very slow, but usually, they grow healthy. Moss balls can establish a healthy aquarium environment as they are capable of absorbing nitrate and producing oxygen.
Frogbits are floating aquatic plants, and they have Lily pad shaped leaves. These plants are also perfect nitrate remover and can establish a healthy aquatic environment. But these plants grow very fast and require trimming. Like all other floating plants, they have a unique aesthetic appeal.
Water Lettuce are larger floating plants with long square leaves. These plants are visually beautiful and nicely decorate an aquarium. You can keep them in your aquarium to reduce nitrates as well.
Duckweeds are floating plants with round leaves. These plants grow very fast, and your aquarium will be full of an innumerable number of leaves in a quick time. Therefore they are excellent in nitrate absorbing but at the same time require frequent trimming.
Water Sprites are a kind of fern with attractive leaves. Meanwhile, submerged plants are better for nitrate reduction than floating plants, and Water sprites are excellent for this purpose as they grow very fast. But they require trimming; otherwise, they might take over your aquarium to make a jungle.
In nature, plants play a vital role as a part of the ecosystem; similarly, live aquatic plants can establish a biological cycle that keeps the aquarium environment healthy and stable in a fish tank.
Fish and other aquarium inhabitants take dissolved oxygen (DO) from water and produce biological wastes. Ammonia, nitrates, and carbon dioxide are the ultimate forms of organic wastes.
In contrast, aquatic plants can absorb ammonia, nitrates, and carbon dioxide as their nutrients and produce oxygen through photosynthesis.
Live plants through their leaves can absorb dissolved pollutants, and at the same time, they take biological nutrients through roots from the substrate. Thus live plants are capable of purifying the aquarium water and eliminating harmful matters from the substrate.
Live plants can establish a healthy natural cycle in aquariums to perform biological filtration, reducing the requirement of cleaning and maintenance.
Live plants create a natural environment in aquariums that makes fish and other inhabitants feel better. A natural home can give them feelings of security and comfort as they get places to take shelter and rest.
Last but not least, live aquatic plants can make your aquarium visually appealing. They can enhance your aesthetic pleasure in such a way that no other decors can do.

While selecting live aquarium plants to reduce nitrates, the first criteria should be their nitrate absorption capacity.
Submerged plants are better nitrate absorber than floating plants, as submerged plants can take dissolved nitrates through leaves as well as through their roots. In contrast, floating plants are capable of absorbing nitrates through their roots only.
Fast-growing plants are excellent nitrate absorber, so if you can select fast-growing plants and submerging plants, they will be sound nitrate absorbers. Water sprites or Java fern can be an excellent choice considering this point.
As living beings, aquarium plants require maintenance like all other aquatic pets. If you cannot keep them healthy, dead leaves or stems can pollute the aquarium environment. So it is better to select plants that are easy to maintain.
If plants are fast-growing, regular trimming will be essential, or they will build a jungle quickly. Usually, floating plants like frogbits are fast-growing and cover the whole aquarium in a short time.
Live aquarium plants can enhance your aquarium’s beauty in a way that no other decors can do.
They can add an attractive natural look to your aquarium. So, the aesthetic is another important consideration while choosing the best aquarium plants to reduce nitrates.
All live plants require light to flourish. Proper lighting can make them healthy, promoting photosynthesis. Plants add oxygen to the water through the photosynthesis process.
Some aquatic plants need a high light environment to grow properly, while many plants need only medium and low light situations.
So light available in your aquarium is an essential consideration while you are picking live plants.
Live aquatic plants in an aquarium naturally absorb nitrate as a nutrient. Submerged plants can absorb dissolved nitrates by their leaves as well as by their roots. In a favorable condition, live aquatic plants can help a lot to reduce the nitrate level in aquariums.
You have to make sure live plants are healthy, otherwise dead leaves and stems can be contributing factors to add more nitrate, which will do evil instead of doing good.
It depends actually! In fast-growing plants, the nitrate absorption rate is higher compared to others. In the best cases, aquarium plants can absorb five ppm nitrate per day.
If you take reasonable measures to control nitrate formation sources and nitrate formation is rate is not that high, hopefully, you will be able to keep the nitrate concentration from 10 to 25 ppm, and that is acceptable.
Nitrates are nutrients to plants. But if the nitrate concentration is too high and above 150 ppm, that can be harmful to plants. ‘Nutrient burn’ is the effect, and plant roots suffer from it, and become unhealthy.
On the other hand, excess nitrate can cause algae growth, and too high algae in the water can cause asphyxiation for plants, and they might demise.
Having live plants in the aquarium is an excellent idea. Plants can create a natural aquascape and can establish a natural ecosystem. Plants enhance the visual appeal of an aquarium and make a natural habitat for aquatic pets.
We hope this article will be helpful in your venture of searching for the best aquarium plants to reduce nitrates.
Healthy aquatic plants are capable of lowering unwanted gas like nitrate, carbon dioxide, and ammonia at the same time, and they add oxygen to your aquarium.
An oxygen-rich aquarium is a healthy home for fish and other species, and that is your ultimate desire as an aquarist.
Hello, everyone! Welcome to my aquarium blog. Fishkeeping is my passion, and I started this fascinating hobby back in 2006. Besides my engineering profession, I deeply studied many fishkeeping topics since I started building my home aquarium. I researched effective aquarium filtration and lighting of planted aquariums. I am keeping 20+ species of freshwater and saltwater fish as my aquatic pet collection. I successfully experimented with a complex ecosystem inside the aquarium, biotope aquariums, aquaponics, etc. I would love to share some learnings from my hands-on experience of the last 14 years. Hopefully, my sharing will be somewhat helpful to make your aquarium journey awesome!
