Hats off to the both of you for informative posts!
Seattle - It is beyond me if the CO2 is dissolving. I will definitely check the pH of the tank when I get home.
niko - 'Glad you took to time to thoroughly explain that process. I have actually used the small reactor you suggested in the past (if it is the small, black filter I'm thinking of). It worked very well but it eventually quit working for some reason.
I guess I'll explore alternative options to dissolving CO2. Obviously, I'd rather not invest too much money to find a good product. I'd like to find somthing for $30 or under. 'Surely I can find something good for that price.
Again, thanks a bunch for the info.
