I was searching Ebay and I came across this:
http://cgi.ebay.com/Electric-Electronic-CO2-Generator-Producer-Aquarium_W0QQitemZ120299652672QQihZ002QQcategoryZ20754QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
Has anyone ever used a product like this? It says that it produces CO2 through electrolysis. It is cheap, but does it work? I am skeptical, but the box looks like it has a picture of an aquarium on it. If it does work, how much CO2 can it produce?
