Still don't get PH

So is PH set by the ration of Calcium, Alkalins, and Magnesium?

PH in my tank is lower than I want 7.91

Calcium is 501
Alk is 9.8
Mag is 1300

So what do I change / add to raise PH?
 
Is it stable at that ?
Does everything appear to be doing well?
You could use a DkH buffer but if everything is going well I wouldn't mess with it
 
Don't buffer!!

Don't worry about pH, worry about keeping levels stable and where you want them and then make sure your water is aerating enough. Make sure there is ample surface agitation and a good air supply for a skimmer, and you'll see the pH creep up.

My pH is stable at about 8.1, and I have levels high-ish all around, and my corals love it, both SPS and LPS.
Cal 550
Alk 11
Mg 1400

Also, are you running a refugium? Keeping a 24/7 or at the least an alternate DT to fuge light cycle will help stabilize the pH from day/night cycles.
