Court grass and water grass need carbon dioxide to grow. As a kind of aquatic plant, court grass mainly absorbs carbon dioxide for photosynthesis. They can absorb carbon dioxide and release oxygen when they are exposed to sunlight. Carbon dioxide is as important to them as food for growth.
They can survive without carbon dioxide, but they may not grow well. Not only will the growth rate become slow, but also may lie on the bottom of the tank no longer stand up, or the leaf color becomes dark, no longer shiny, listless. Therefore, when cultivating aquatic plants, it is necessary to ensure that carbon dioxide in the tank has a certain concentration, and it is better to use carbon dioxide bottles to input carbon dioxide into the tank regularly.
The growth of the palace grass and water grass needs oxygen, but it does not need oxygen. Aquatic plants are often placed in fish tanks, in addition to certain ornamental value, but also because they can provide oxygen to the fish tank. As a kind of aquatic plant, court grass can photosynthesize in the case of sunshine. They absorb carbon dioxide and release oxygen. Therefore, although it is necessary to maintain the oxygen content in the cylinder, it is not necessary to input oxygen to the royal grass.
