The bubbles produced by aquatic plants are oxygen resulting from the process of photosynthesis. When water becomes saturated with this oxygen, the gas is released from the plant's leaves as tiny, visible bubbles, a phenomenon known as "pearling". This is a sign of a healthy, thriving plant producing more oxygen than the water can absorb at that moment. What the bubbles mean: Photosynthesis: The bubbles are a byproduct of photosynthesis, where plants use light to convert carbon dioxide and water
