Here is another video of my tank where I demonstrate what I have just disovered this morning. That aquatic plants produce much oxygen when exposed to direct sunlight and when covered even for a few seconds they would slowdown or even stop producing oxygen bubbles. But when again uncovered they resume releasing much bubbles. :-)
