Diagnosing Sudden Alkalinity - Is this normal?

[FishyFishy!]

You should be able to raise and lower your alk about 1dkh per day. Anything more than this and you could see issues. I dont really see much wrong with what is going on. Your dkh is actually quite good. Mine is terrible, if im not dosing I can easily see 1-2 dkh swings in a day.

PH is actually very relative to alk dosing. Depends on what you are dosing, it will definitely have an effect on your PH in the positive or the negative.
