Re: [AGA Member] CO2 concentration in Hard water

Amit,

I don't think that Red Sea's info was incorrect, but their choice of words is
unfortunate.  "Adsorb" creates the image that the water will suck CO2 out of
the air, and it will do that more if the KH is higher.  It does not.  You
still have to add the CO2 to the water.

Scott,

Sorry, there should have been a smiley after the "picky" comment.
