Another video demonstrating what I just discovered this morning that under direct sunlight, aquatic plants produce much oxygen bubbles but when covered even for a few seconds they would slowdown or stop producing bubbles. But when exposed again to direct sunlight, they again produce much bubbles especially Pearlweeds.
Did another experiment with my sun tank. I wanted to know what would happen if I did not infuse co2 on the tank, would the Pearlweeds still produce bubbles under direct sunlight? Its been thrsee days since I stopped giving pressurised co2 to the tank and I have observed that the Pearlweeds still produce bubbles in the morning when the sunlight hits them directly and continues to do so in the afternoon even when the sunlight is not directly on them.
