I believe the system you may be looking at uses a yeast and sugar for
producing the CO2

I'm looking into CO2 and found a system which does not require a CO2
bottle..It uses a tablet or something.

Can anyone explain how this works and the CO2 in general please and
wether I
have to purchase tablets from the supplier at a inflated cost or
wether
there is an alternative.

Thanks in advance
