How to raise PH without Raises AK

[MRCORAL]

Is this impossible? I got a new Pinpoint and my pH is around 8.05 Max during the day. I have been putting pH Kent Marine pH 8.3 Buffer to raise it. It goes up to 8.15 then the next day it can never get back to that level. All corals and fish are doing well. However, I tested my AK and it is 14 now which is high. Any ideas?

8.05 is fine. i would stop the buffer though.

open up some windows or run your skimmer intake to fresh outdoor air

My Pinpoint always reads lower than a Salifert test. I'll get 8.2 - 8.3 on the Salifert, while the Pinpoint will show just over 8 like yours does. Anyone else notice this?

So which one can we trust?

That article talks about low pH issues. More aeration or less CO2 in the air might help.

I'd trust the meter, if it's been calibrated recently. Electrical interference can be an issue, though.
