Re: [APD] Re: Pressurized CO2 Equipment

["S. Hieber" <shieber at yahoo_com>]

Put that way, I'm inclined to agree, Dan. But still I would
caution anyone beginning with pressurized CO2 to do some pH
and KH tests until they have a good sense of what xx many
bublles per minute means in terms of CO2 levels on a given
aquarium set up.

Since there is such thing as too much CO2 in a fish tank,
it's best to start low and work up rather than the other
way around.
