Best Aquarium Plants Reduce Nitrates For Your Fish Tank

The great importance of nitrate in the aquarium is arguably less perceived by fish keepers than the effect of ammonia and others in general. Even though nitrate is not as directly toxic as ammonia, from time to time, high levels of nitrate detrimentally have a great impact on fish and the aquarium environment on the whole. If this ion is that dangerous, how can you scientifically reduce it? Actually, you are technically capable of reducing the content of nitrates in water by applying plants. There are the top 5 of the best aquarium plants reduce nitrates that basically can assist you with the nitrate reduction as much as expected.

How to choose a best aquarium plants reduce nitrates ?

There are several types of plants that can help you to reduce nitrate content in your aquarium:


Undoubtedly, duckweed is one of the best plants for making use of and absorbing nitrates in the water among those. This thing is like tons of miniature Lily pads that are beautifully connected together. It’s a perfect option for a tank that has some floating plants and for fish that like having some cover or shade in the aquarium. 

Regarding using and absorbing nitrates, duckweed is absolutely a good choice. It is actually fast-growing and it multiplies in no time, and hence it has a tendency to eat up a lot of ammonia, nitrite, and nitrates also.

What is convenient about duckweed is perhaps that it is easy to grow without much effort or taking care. As far as the water is fairly clean, it is inclusive of some nutrients, and you provide it with some light, duckweed will grow like weeds. As far as we all know, it is one of the best natural water filters that are available, and it looks nice as well.

Bear in mind that this stuff grows fairly fast, so one minus point might be that you have to trim it quite frequently to keep it from overtaking the tank. Nonetheless, other than that, there are no real issues that you will encounter with duckweed, maybe apart from the fact that fish like to eat it sometimes.


Frogbit looks like the duckweed somehow, being the first plant for nitrate reduction that you looked at. They basically feature rounded green leaves floating on top of the water all the time. This does grow fairly fast, which again can be both pros and cons. On the one hand, you will have to trim it fairly often to stop it from overtaking the tank. Letting this stuff grow too much can lead to way too much cover that blocks loads of light from getting into the tank. Nevertheless, the fast growth of it helps make it a good aquarium filtration plant for sure. It absorbs a lot of ammonia, nitrites, and nitrates from the aquarium, which is of course what you are going for here and me as an instructor as well.

Best Aquarium Plants Reduce Nitrates FAQs

Are there any other ways to reduce nitrates aside from using plants?

  • Keep the aquarium clean: Waste actually produces nitrate; cleaner aquariums produce less nitrate that needs to be pulled out by water changes.
  • Feeding amounts: Overfeeding is a primary contributor to making nitrate and other undesirable wastes, like phosphate excessive.
  • Water changes: Doing regular water changes with water that has little or no nitrate will significantly reduce the overall nitrate level in the aquarium as sure as hell. If your local tap or well water is a little high in this kind of content, using deionized water or reverse osmosis water helps keep nitrate levels low when you are performing a water change. Nonetheless, because these are empty from minerals, the hardness, alkalinity, and pH of the water can turn too low and mineral supplements may have to be added instead. Mix your nitrate-containing tap water with those aforesaid types of water to make a blend with the correct water parameters before the reduction process.

Where does nitrate hail from?

Nitrate is obviously a waste of nitrite oxidation within the latter stages of the nitrogen cycle and it is visible to some degree in all aquariums. Detritus, decaying plant material, or dirty filters, or even over-feeding all greatly contribute to the higher levels of nitrate involved.

In addition, tap water that is normally used to fill the aquarium may contain nitrate as well. In the US, drinking water may contain nitrates with 40 parts per million (ppm). Prior to adding water to your aquarium, test it for nitrate to check if the levels are unusually high in your water source or not. If your baseline nitrate is higher than 10 ppm, take other water sources into account that are nitrate-free.

What are the adverse effects of nitrate on fish?

Fish will sense the influence of nitrate by the time levels actually reach 100 ppm, specifically if those levels persist. The resulting stress causes fish to be more susceptible to disease and inhibits their capability to reproduce.

High nitrate levels are extremely harmful to fry and young fish and will detrimentally affect their growth. What is more, the same conditions that lead to elevated nitrate often cause decreased oxygen levels, meaning fish will be further stressed out.
