Can Aquatic Plants Produce Oxygen? A Detailed Explanation of How Aquatic Plants Oxygenate Water

Aquatic plants are extremely useful plants, a collective term for many aquatic plants. They not only greatly enhance the ornamental value of fish and promote the growth and reproduction of tropical fish, but also serve as shelter and refuge for many aquatic animals, together with aquatic animals, substrate sand, and water creating a circular ecosystem. Let's take a look below at whether aquatic plants can produce oxygen!

Can Aquatic Plants Produce Oxygen?

Aquatic plants can produce oxygen. Under light, aquatic plants continuously release oxygen into the water, and likewise into the bottom layers of the aquarium. Frankly speaking, no artificial equipment can perform the same function. In an aquarium, oxygen is usually released into the water in a dissolved form, but in some cases it is visible, for example tiny oxygen bubbles may rise from damaged leaf surfaces to the water surface.

Can Aquatic Plants Purify Water Quality?

Aquatic plants can purify water quality. In an aquarium, aquatic plants and ornamental fish cooperate with each other, complementing and enhancing each other. Under light, aquatic plants absorb carbon dioxide from the water for photosynthesis, release oxygen, and supply it for aquatic animals to breathe. Aquatic plants also absorb nutrients from the water, reducing organic pollution, thereby purifying water quality. They can also provide hiding places for timid fish and shade light for fish that dislike strong light.

What Are the Benefits of Growing Aquatic Plants?

1. The metabolism of fish in the aquarium and the decomposition of feed easily produce large amounts of ammonia and nitrite, which through action form nitrate. Nitrate is not decomposed and accumulates in the water, causing water quality to deteriorate and destroying the entire aquatic living environment. Aquatic plants have the function of absorbing nitrate, reducing the accumulation of nitrate in the water and purifying water quality.

2. During their growth process, aquatic plants can release effective antibiotics, killing bacteria and pathogens in the water, reducing the content of harmful microorganisms in the water, protecting fish from bacterial invasion, and promoting healthy growth of fish.

3. Aquatic plants can absorb minerals, carbon dioxide, organic matter, etc. from the water and process them. While processing, they reduce harmful substances in the water and reduce water pollution. They can also produce oxygen through photosynthesis, increasing the dissolved oxygen content of the water, thus directly providing the driving force for the survival of fish and other organisms and balancing the overall state of the water quality.

4. The most important function of aquatic plants in an aquarium is to enable fish to reproduce in the aquarium. Some fish especially like to lay their eggs on the leaf surfaces of aquatic plants. Without aquatic plants, juvenile fish would have nowhere to hide in the aquarium and could be attacked by large fish that prey on them.

5. Planting densely growing healthy aquatic plants in an aquarium is the best way to prevent algae from spreading, because when competing with algae for nutrients, aquatic plants have a significant advantage. Of course, the prerequisite for aquatic plants being stronger than algae is that they must grow and reproduce in a strong, healthy manner within the aquarium.
