I have never had any dealings with co2 systems and have been looking through the forums without any luck finding anything about how they work. could someone please explain them, or at the very least link it to me? Thanks.

Do you mean how do they produce CO2 and how do you get it dissolved or what the CO2 does for the plants?

There are two basic types, one method is to dissolve sugar and yeast in water, The yeast consumes the sugar and produces ethyl alcohol and CO2. Attach that container to the tank through an air tight container and air hose. The CO2 is then released through an airstone or some type of reactor to dissolve it in the water.

The second way is to attach a food grade CO2 tank to the tank, through a reducing valve, the CO2 is dispersed in the same way as above. This way is expensive at the start but allows precise control and no need to mix up new yeast mixtures every few weeks.

The plants use the carbon along with light and other nutrients to produce sugar and to grow.

Hope that helps a bit.
