14 Best Fast Growing Aquarium Plants (without CO2)

If you are looking for the best fast-growing plants that can grow without CO2 then you are at the right place.

Now let me clear one thing first. 

All the plants that I have mentioned in this article can easily grow pretty fast without CO2.

CO2 just makes them grow faster. 

So if you want to grow these plants even faster then you can supplement them with CO2.

You can speed up the growth of plants by introducing fertilizers as well (I have talked about it in detail below!)

With that out of the way, let’s start the list!

Conclusion

So these are the best fast-growing plants that you can grow without CO2.

I personally think any aquarium is incomplete without plants.

There are a lot of benefits of keeping live plants in an aquarium.

They help to lower the ammonia levels in the aquarium which is very harmful to the fish.

They help to increase oxygen in the aquarium.

Fish like live plants in their aquarium because it emulates their natural habitat and some fish like Goldfish sometimes like to nibble on it.

Overall, live plants help to maintain a healthy aquarium.

If you are a beginner there you should check out my guide related to taking care of live plants in aquarium.

I hope you found this article helpful.
