One thing it does not do is oxidise carbon to CO2. It _may_, in
hard water, precipitate out CaCO3 and produce CO2 that way.
Ca++ + 2HCO3- -> CaCO3(solid) + H2O + CO2
A CO2 cylinder setup is, as far as I am concerned, the easiest
and quite possibly the cheapest (long term at any rate) way of
introducing supplemental CO2 into an aquarium. With a capital outlay
of about $170 Canadian, $20 refills at four year intervals and no
work involved, it's difficult to beat.
