You can bubble your own CO2 with yeast, sugar and water in a 2 liter soda
bottle. It's a pain to keep feeding the yeast, but it's pretty cheap and
does a good job for many plants. Google "DIY CO2" should get some info
to you.

About half way down that page is a section where the guy posted pictures
and instructions on how to make a DIY CO2 generator. I found that article
while researching for a reef tank. I made one two nights ago and it works
good. Too good in fact. I double dosed the yeast trying to jump start my
plant tank and ran into a problem worse than recharging the yeast. Trying
to regulate the CO2. Instead of bending a stiff piece of tubing, I simply
used flex tubing and ran it through the bottom of the strainer (after
drilling a hole for it). The problem is that it produces so much CO2 that
the bubbles actually build up and cause my filter to "dry run" for about a
half a second every minute or so. I am going to have to put a T in it and
split it up. Impossible to regulate.

Thanks Randy but I really don't have the time to mess with something like
that. I can kill all my fish if I make a mistake.
