 If you are on a budget and your tank isnt more than 30 gallons or so, you 
can build your own comparable CO2 generator for the price of a 2 liter 
bottle, some silicone, and some airline. There are alot of plans online that 
are more detailed, but the basic idea is to either drill or poke a hole in 
the cap of the 2 liter. The hole should be as close to or slightly smaller 
than the size of the airline. Clip one end of the airline at an angle. Insert 
about an inch or so of the tubing into the cap and silicone the heck out of 
it. We want it to be airtight. After allowing about 24 hrs for the silicone 
to cure,
we will pour 2 cups sugar, 1 tsp baking soda, 1/2 tsp instant yeast into the 
2 liter. Then fill to just about 2 inches from the top of the bottle. Insert 
the other end of the airline into a powerhead, HOB filter, anything with an 
impeller that will break up the CO2 bubbles. After a day or two you should 
begin to get bubbles. When this happens, monitor your pH levels, compare this 
along with your kH to the CO2/pH/kH reference table at www.sfbaaps.com. This 
system will require some fiddling probably.
The CO2 brew will need renewed every couple of weeks. Again, monitoring your 
pH will tell you when to change it. 

This system works well, but I got tired of it after a year or so and went to 
compressed gas CO2. Its a little bit of an investment at the start, but it is 
well worth it.

Good luck, dont give up, read the archives, etc.
