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

Increasing oxygen in the aquarium in one of them.

There are some other ways to increase oxygen in the tank. For ex., using an air pump, cooling down the water in the aquarium, etc. (Check out our recommended Air Pump)

But keeping live plants in the aquarium is a very natural way of increasing oxygen in the water column.

Just like on the land the aquatic plants photosynthesize to create their own food and during the process, they will release Oxygen and consume Carbon dioxide produced by your fish.

Plants also take advantage of uneaten food and fish poop for their growth.

They basically use it as a fertilizer.

There is a common myth in the aquarium hobby that when the plants release carbon dioxide during the night it can harm the fish in the tank or pond.

But the reality is, plants release way less carbon dioxide that it will not harm your fish.

Besides oxygenating the aquarium, live plants also help to lower ammonia as well as reduce the temperature in the aquarium.

What aquatic plants produce the most oxygen?

All the aquatic plants produce oxygen.

But submersible aquatic plants introduce more oxygen in the tank then the floating plants because they release oxygen directly in the water column.
