OK i just started a research project for my honors biology high school class. Does anybody have an idea for how to grow some common algae in a matter of days (or shorter??) I have lots of algae in my fish tank but none in my test jars. I have tried adding nutrients (miracle grow) and i have added light (a grow light) i still am not getting any algae. I even planted some algae from my tank. Is the problem air. If so how can i add air equally to each jar??
