Is it possible to simplify the BBB method even more?
From my days as a chemist, I know that NaHCO3 is a buffering agent, helping to keep the pH of a solution steady. If I am willing to add acid or base every day (like I add bleach every day), do I need to bother with buffering? I ask because I'm having trouble getting both my pH and my Alkalinity correct (Alkalinity is within range, but my pH is a little too high; adding acid hasn't had much effect due to the buffering of the bicarbonate).
Does the bicarbonate do anything critical besides smooth out changes in pH?
