Using CO2 tablets for nano tanks?

[aquaSynthesis]

Has anyone tried this method for small <1ft tanks? Was thinking of doing this method before I fully go high tech..

Any feedbacks welcomed.

i tried the $3 one at polyart before i went to DIY CO2. the CO2 tablets seem to be ineffective as in there seems to be little CO2 produced. and the small chunks of the tablet will float around.
i would suggest DIY CO2. it saves more time as you would only need to change the solution once every few weeks rather than adding the tablets all the time. CO2 tablets also fluctuate the PH more seriously than DIY CO2
