Re: [AGA Member] CO2 concentration in Hard water

Sorry, Roger,

Don't mean to seem picky and I'm not taking issue with you.
I just wanted to be clear on the distinction. 

It makes a diff in how some folks understand the
relationship -- some think that you can raise the CO2 level
merely by raising the KH or (or having a high KH) -- like,
to stretch a simile, getting a bigger sponge allows you to
soak up more water.

Thanks for another lesson, :-)
