Ok so obviously excessive CO2 in a tank creates carbonic acid thus lowering the pH. But if you have both low pH and low alkalinity will the alkalinity raise by correcting the low pH problem? For example, I added a CO2 scrubber to my skimmer. As the pH goes up from the absence of CO2 will the alkalinity raise on its own with the pH or will I still have to dose alkalinity to bring it back up to the adequate level?
