You dont necessarily need it, but you might want it if you have a tank with high light levels. I run planted tanks without it and have done for a few years.

There are different ways of doing it, ranging from simple fermentation of yeast delivered from a bottle to pressured cylinders of gas. Its hard to do justice to it in one post. Google it and read around the subject a bit.

In the meantime, what is your set up (tank size lights etc) and what plants are you growing?
