DIY CO2 Generators

Do I dare ask a simple question, I ask myself rather sheepishly?

I'm a virgin aquatic gardener, and I've been reading everybodies
references to CO2 addition to the water to improve plant growth. Is
anyone willing to tell me how to do it? What does it do to your fish? The
plant thing is actually an afterthought, but I'm thinking about starting up a
second tank with the sole purpose of growing  aquatic plant's.
