I really appreciate what I have read so far--thanks.

I am still trying to grasp my fluctuating pH over a week it will drop from 8.3 to 7.7. I am aware that carbon dioxide plays a big part in this. However I just read above that a stable alkalinity level will help maintain the the stability of the pH level. My alkalinity has been stable at 8.5----and in the past I have had it as high as 13.dKh(stable) but the same fluctuation in pH occurs?

Opening windows etc will raise the pH slightly but not really that much. I used to use the kent reef builder but I am aware that it raises the alkalinity also(this is how I ended up with 13 dKH)
I am also aware that I could use Kalkwasser to build up the pH and not the alkalinity.
I am confused at what route to take?
