Re: [AGA Member] Water question..

["Amit Brucker" <amitb@gtek.co.il>]

I know of course that CO2 had a direct effect on PH, However  I am more
interested in the connection of KH and CO2, as it seems that high KH levels
can contain higher CO2 levels than lower KH levels.... And since what effect
KH are carbonates and bio carbonates and that plants may use (Maybe I get
this one wrong...) I was wondering whether less water changes will lead to
decrease in the KH levels as CO2 will drop. (thus while maintaining a stable
Ammonia/nitrite levels).
Hope I've made my self clear
